Thanks now I understand. (I'm not english).
You should update your Msg Plus to v3.61 , it fixes many bugs about tabs and others.
I Have Windows Xp too, I use Msn Messenger 7.5.0306 and Msg Plus 3.6; but I can't use handright! I simple can't draw !
But if ypu can draw, try to update to Msg Plus 3.61
