Hi All,

We (Momentics IDE team) are trying to focus on fixing CDT debugger for this release, as a part of the effort we have 
some experimental fixes we would like you to try.

Please check latest IDE build 20080117 on foundry: http://community.qnx.com/sf/wiki/do/viewPage/projects.ide/wiki/
Whats_New_IDE_Tau
(no update site for this version).
This page contains summary of debugger fixes for this build. 
It does not fix slowness but may fix some other problems such as UI lockups and breakpoints enabling problems.

If you encounter some problems please report them in the forum. We would need gdb console log in this case. 
In this version it can be enabled from IDE by enabling Verbose console mode in launch configuration in Debugger tab and 
later selecting gdb console from console list and saving its output to a file using console actions.
