I'm debugging a project that is using static libraries created in a different workspace.

When the application crashes (on startup) and presents the stack trace, clicking on one of the functions in the library 
produces a screen with:

Can't find a source file at "<filename.hpp"
Locate the file or edit the source lookup path to include its location

(Button) View Dissassembly....
(Button) Locate File....
(Button) Edit Source Lookup Path....

Selecting the Locate File... button allows me to browse and find the file, however, once selected, editor briefly 
displays the file and then immediatly reverts back to the above message.

If I use the Edit Source Lookup Path... it finds and displays the file, however upon setting a breakpoint, I get a 
dialog that says:

Operation failed

Reason
     Missing resource


I'm using the most recent Tau build (4.5), QNX 6.3.2 on Windows XP

Let me know if there is any other information that would be helpful.

Thanks
Kevin
