Comment 1 Darin Swanson CLA 2001-11-07 11:57:51 EST 
Test Case: 
Open the debug perspective
Switch to the Resource perspective
Close the workspace
Open the workspace
Window-->Preferences-->Debug
Change the orientation of the details form.

The debug perspective exists and the variables view is registered as a property 
change listener but the view has not been fully created so the sash bar does 
not exist.
Comment 2 Darin Swanson CLA 2001-11-07 12:19:49 EST 
Fixed by changing when the addition of the property change listener occurs.
Please verify.
Comment 3 Joe Szurszewski CLA 2001-11-07 15:38:07 EST 
Verified.
