118.0. "Mouse problem: Both buttons act like left button" by RAINBO::COUTU (He who will not risk, cannot win.) Wed Jun 08 1988 21:52

    Lately I've noticed that my left mouse button knows what my right
    mouse button is doing! In other words, I seem to have a one button
    mouse. Left button works just fine, right button acts just like
    the left button.
    
    Hmmmm. "No problem!" there's always another way to make it work,
    right? Now, that's ALT-Insert for the left button and ALT-Home for
    the right button. Same behavior! It would seem to be a problem not
    with my physical switches (or card) in my mouse.
    
    So I solicit ideas from the crowd. Could it be that some chunk of
    software is mangling the interpretation of keyboard processing so
    that both buttons get mapped into one? Could it be that my keyboard
    processor hardware is snafu? Any thoughts on the matter are welcome
    and solicited. Some apps actually insist on the right button and
    these are not real useful to me right now.
    
    Thanks,
    
    Dan

118.1	More likely a software problem...	LDP::WEAVER	Laboratory Data Products	`Thu Jun 09 1988 00:24`	10
	Sounds like a problem with the keyboard processor (6301), but I doubt it. More likely you have installed some software that is causing the problem; did it happen after you started using a particular piece of software? Does the desktop exhibit the problem? Try powering down your machine, then power it up without any disks attached/inserted, wait for it to timeout to the desktop and see if the problem still persists. If the problem remains after all this, then it is probably the 6301. -Dave

	Okay, sounds like a good suggestion. I'll give it a try tonight and see what happens. Dan
118.3	One possibility	PRNSYS::LOMICKAJ	Jeff Lomicka	`Thu Jun 09 1988 17:26`	22
	Whack (or any of my other applications) could be at fault here. When using GEM, you are allowed to request left button events, right button events, or events that have both buttons pressed. You may NOT request "either left button or right button" as an operating mode, which is, of course, the only mode I'd ever want to use. (Stuuupid, stupid, stupid. I'd like to ring the neck of a DRI engineer for this one.) In order to get reasonable access to the left button, that is, left button OR right button instead of left button AND right button, Whack splices into the interrupt vector for mouse handling, and converts all right button events into left button events, and keeps it's own event queue. GEM is then happy to report right button events for all mouse events, and I look in my own queue to see what really happened. As a side effect, any desk accessory you are running with Whack will not be able to access the right button. The interrupt vector is put back when Whack exits, so it SHOULD return to normal. Note that if Whack bombs instead fo exits, it will leave this code behind.
118.4	Eureka!	RAINBO::COUTU	He who will not risk, cannot win.	`Thu Jun 09 1988 21:52`	12
	Whack is the answer! I had recently set it up as a desk accessory. I find it handy to be able to switch quickly between Uniterm and Whack (they each have their specialties) and the DA made it real easy. Well, since the DA never exits it keeps the interrupt vectors modified forever. Guess I'll have to go back to using the PRG version of Whack instead. :-( Thanks for info, Dan
118.5	I'll put it on my list	PRNSYS::LOMICKAJ	Jeff Lomicka	`Fri Jun 10 1988 14:19`	5
	Whack rarely uses the right button - I will see if I can arrange for this "feature" to be off most of the time, and turn it on only when the window with input focus is using the right mouse button. (Not an easy change, but well worth the effort, I suspect.)
118.6	Thanks for your support!	RAINBO::COUTU	He who will not risk, cannot win.	`Fri Jun 10 1988 20:51`	6
	Sounds like a good idea, until then I'm using the .PRG version and will keep an eye out for your postings about Whack. Thanks, Dan
118.7	Different methods?	LDP::WEAVER	Laboratory Data Products	`Fri Jun 10 1988 21:31`	6
	Re: .5 There is some code that Atari has made available which makes both buttons work, I will see if I can find it and send it to you. -Dave
118.8	Two buttons are better than one	MILRAT::WALLACE		`Mon Jun 13 1988 16:32`	8
	Dave, Sounds like something more than one of us would be interested in. So could you either post it here as a reply (if it's short) or make it available for copying? Thanks, Ray
118.9	When a solution is not a solution	PRNSYS::LOMICKAJ	Jeff Lomicka	`Wed Jul 20 1988 16:32`	6
	I got the "official" two-button patch from Dave, and was disappointed to find out that they use the same method I do. Using the Atari code would have the same drawback - desk accessories would see both buttons as the left button. Back to the old drawing board.
