I have 10 Object Docs - two a the bottom and 8 on the left (tabbed as drawers ).  If I update anything in WB such as color change, when it comes back from the gray screen (please wait....) I only have the two on the bottom and one of the drawers.  OD thinks it has them all because they are all listed and the little bouncing arrow bounces where they SHOULD be, but they're not there.  I unload OD and start it again and voilla - they're back.  The current desktop is on my page.  Any ideas on this? 

WB 6.1 Build 49 x 86   OD Version 1.90 Plus Build 535u  XP-SP2
