Seeing there are already 2 threads about bugs in Messenger Plus! 3.40 (beta) and probably soon will follow more they should be brought all together in one thread. This is easier for people who found a bug but don't know if it has been reported already or not.
First bug:
The personalized status tag appears not be working with MSN Messenger 7 (beta)

Second bug
Contacts can't be dragged to another group. If they have colours in their name and u try to drag them to another group you can't see these colours anymore until you close and reopen the group list.
Seems to be for MSN Messenger 7.0.0225 (beta) and seems to be working good for 7.0.0332.

Please make sure you use the latest version of MSN Messenger 7 beta (7. 0.0425) if you report a bug while you use Plus! 3.40 (beta) with MSN Messenger 7.
Always give the version of MSN Messenger/Windows Messenger you are using + your Windows version.
Update: Please
don't report any problems with Plus! 3.40 beta if you are using MSN Messenger
7.0.0604. It is known that some things don't work the way they should work. It will be solved in 3.50 (which will be released in about a month).
