Again, this did not happen in 4.4.

I use opera with several windows open at once, and all of the windows grouped together. Now, whenever something happens in one of the windows (for example, one of the sites in that window tries to set a cookie, which triggers a warning), the window detaches from the group and takes its own place in the panel.

It seems that the only way I can get the window back into the group is to do "Advanced / Do not allow this program to be grouped" followed by "Advanced / Allow this program to be grouped". The problem with doing that is that the group always reorders itself (from top to bottom) in an sequence I don't want.

Some questions:

1. Is there some way to prevent a window from detaching itself from a group (going back to the kde 4.4 behavior)?

2. Is there a better way to put a window back into a group?

3. Is there some way of reordering items in a group (and likewise changing the order applications appear in the panel)?
