Alright, so I have the Spanish (Latin) version of Msg Plus! (3.60.144) and there seems to be something wrong whenever I switch windows when I'm using the tabbed conversations feature... Every time I switch from window to window in my convos, the window seems to get smaller (vertically) every time I do that, and once it gets as small as it can, it gets bigger horizontally. Any suggestions on what I can do? Or is there something that I'm doing wrong? o.O Thanx in advance!

This problem has been reported several times in several threads already. Do you have by any chance windowsblinds installed? If so, that's the culprint. Not much can be done to fix this as this is a bug in Windowsblinds itself.
