[wingide-users] Missing breakpoints & projects

I've just discovered a new (to me, at least) mechanism that seems to explain 
why WingIDE seems to ignore breakpoints from time to time. Perhaps everybody 
else already knows this, but it is a surprise to me. I don't want to report 
it as a "bug" yet, because I might be mistaken, and it might even be a 

I'm working on a large, object-oriented framework. I have recently started 
using projects to organize "assemblies" (collections of related classes) 
within that framework. I thus have multiple projects, each with a disjoint 
set of classes. I've just verified that the breakpoint settings within a 
particular class (file) seem to be stored in whatever project is active when 
the breakpoint is created.

The bug/feature/phenomena occurs when I do the following:
1. Open projectA.
2. During debugging, open class B.Foo, contained in projectB.
3. Set a breakpoint somewhere in B.Foo
4. Save projectA.
5. Terminate the current debugging thread
6. Open projectB.
7. Start a new thread, hoping to stop on the breakpoint created at step (3), 

To my surprise, the thread created in step 7 will NOT stop. This is because 
it appears that the breakpoint I created is visible only to projectA.

I'm not confident that this is precisely what happens, because I haven't 
played with it much. For example, it might be that the "enabled/disabled" 
checkbox is what varies between projects. I have, however, verified that 
SOME connection exists between breakpoints in a file and the projects that 
contain that file, this is news to me. I always thought, rightly or wrongly, 
that there was ONE class file and ONE set of breakpoints (and their status) 
unique to that file. This is apparently not the case in this version 
(v2.1.4-2) of Wing IDE Professional.
