1470.0. "Cannot draw lines on MAP background" by CSC32::WOESTEMEYER (Why??...Why not!!!) Mon Sep 09 1991 14:35

Interesting question/problem.  Create a domian, copy a map backdrop 
to the domain name as specified in the Director Use Manual.  Reenter MCC 
and try to use the tool box to create a line in the map.  All seems to
work fine until MB1 is release.  At this point the line disappears 
and the outline that was surrounding the line goes fuzzy.

Saving the map, exiting and reentering, does no good, line still does not 
appear.  A differences between the domain specific map and the templete 
in MCC_MAPS shows no difference in the files.

Any ideas out there?

1470.1Not Alone.KERNEL::OSBORNEMon Sep 09 1991 15:0315
    Steve I had just had a similar problem where all my backdrops
    disappear and wwould not reappear until I rebooted!. I have just tried
    to recreate the problem you are getting but found that the Line
    remained just as I had drawn it.
    
    I have recently been on a BMS course where several students spent time
    designing their Maps, only to find that they had gone away when going
    back into the Domain Window. They then found all was OK after a system
    reboot.
    
    Sorry I don't know why this occurs, but as you say when the map is
    saved in this strange situation the MCA**********etc.mcc_map_* aren't
    modified or created.

Yikes!!  Would you be able to pipe your display to my WS and let me see this
first hand?...It's a new one on me!  Call me DTN 226-5339.

1470.3Same with SMS kitCSC32::WOESTEMEYERWhy??...Why not!!!Tue Sep 10 1991 16:2813
    A little more information.  Fred Messinger (.2) saw this behavior
    yesterday when I piped the display to his work station.  At that time I
    was running the BMS kit for V1.1, since then I have installed the SMS
    kit from the August CDs.  Same behavior is noted.  It seems that if
    lines are drawn in an enclosed area the symtoms are seen, if the
    drwaing is done in the open areas, ie ocean, the lines are fine.
    
    If a line is drawn from the ocean to an enclosed area, it is ok at
    first, then draw a line in the same enclosed area, the second line is
    never represented and the part of the first line in the enclosed area
    is also gone.
    
    Now What??
1470.4More strange behaviourCX3PT2::SHOTO::W_MCGAWTue Jan 14 1992 20:4815
    I have a customer who is trying to connect two domains in his top
    domain by drawing a wire between them.  His top level domain has a
    backdrop of the United States.  The two domains are in New York and
    Maryland.  He selects the line option of the toolbox and then tries to
    draw a line between the two doamins.  The line looks fine until he
    releases MB1.  At that point the line went from its original starting
    point out into the oceanand the two domains disappeared from the
    display.  If he clicks MB1 on either of the window scrolling bars, he
    sees the domains again but they disappear when he releases MB1.
    
    He is running DECmcc-BMS V1.1.
    
    Any ideas or other questions I could ask him?

1470.5Middle to Middle *not* edge to edge...BSYBEE::EGOLFJohn C. Egolf LKG2-2/T02 x226-7874Tue Jan 14 1992 23:1916
	The way  you connect any two icons (like your two domains) with
	a line is  to  select  the  line icon and then put the "cursor"
	(you know what I  mean) *IN THE MIDDLE* of one of the icons and
	drag the line over to  the *MIDDLE* of the second icon and then
	release MB1.

	Too many people are very precise  in  drawing lines between two
	icons.  They go from the *edge* of one icon to an *edge* of the
	second.  If you miss the edge by  just a little, the line isn't
	'attached' to the icon and strange, complex formulas kick in to
	do positioning of the line.

	Go from the middle to the middle and it will  work  every  time
	and look fine, backdrop or not.
