Description Paweł Wierzbicki 2013-04-19 18:14:25 UTC

I wanted to delete the default activity and change it to "desktop icons" in openSUSE 12.3, up to date with standard repos on a Lenovo Thinkpad T61. 
I opened the activities menu, changed "active" activity, accidentally clicked on it's icon and new window opened to choose new icon - but now i'm not sure it was after or before i deleted the activity. Then i closed it and deleted activity. Suddenly panel disappeared for a second and showed again like it was before - fully functional. I tried to make new activity and reproduce this but can't.

Sorry for not much information.

Reproducible: Couldn't Reproduce

Comment 1 Paweł Wierzbicki 2013-04-19 18:19:21 UTC

I can't edit description. It should be:
> I opened the activities menu, changed "active" activity, accidentally
> clicked on it's icon and new window opened to choose new icon. Then i closed it and
> deleted activity. Suddenly panel disappeared for a second and showed again - but now i'm
