[GAP] Seeing double with GPS debugger

[John McCormick]

Next semester I'd like to introduce my data structures students to 
the debugger.  We are using AdaGIDE.  When you invoke the debugger in 
AdaGIDE, it brings up the GPS debugger and initializes it.  The 
source file and the debugger console are displayed.  When I click on 
the GO button, a second copy of the source file is displayed.  The 
two copies of the source file behave differently.   The green 
highlighting that indicates the line about to be executed is only 
available in the second copy.  The red "stop signs" indicating a 
breakpoint are only seen in the first copy.   I can set breakpoints 
on the second copy, but they are only displayed on the first 
copy.  Closing either one of the source copies does not transfer its 
display abilities to the other.   Any ideas on how to change things 
so that I can get both current line and breakpoints to be displayed 
on a single copy of the source file?
