Bug 24080

Description James Moody 2002-09-25 09:09:03 EDT

Started up fresh 2.0.1.
Turned autobuild off.
Checked out 31 projects from CVS. These projects have prerequisites that are 
not in the workspace yet (should be okay, autobuild is off).
Workbench->Preferences
Expand "PDE"
Select "Target Platform".
Everything locks up. Log fills up with:
