I then find it in a different activity. I noticed the following i my .xsession-errors when I looked: Both point size and pixel size set.

Reproducible: Sometimes Steps to Reproduce: 1.Create three or four activities 2. Jump around from activity to activity (it seems you have to do this) 3. Add a widget 4. Try to move it -- it disappears 5. Look at the other activites -- it will be in one of them. Actual Results: Widget ended up in the wrong activity Expected Results: Should stay in the activity it was added to. -- You are receiving this mail because: You are watching all bug changes.
