GUEST: when i change the document group the IDE turns slow to open it

muellermi: switch group

MackSix: Repeatable. Slow switching  Document Groups with 2 Document Tabs with only a few files open.

MackSix: Made 2 Document Groups. Switched to one (It has no Document Tab Groups) and then back to the other (It has 2 Document Tab Groups). There was this large delay switching back.

GUEST: Sometimes,it simply hangs... And then its allright after couple of seconds.
