Pidgin: Possible Bug

I have Pidgin Portable 2.1.1, clean install. When i login to Pidgin its all fine, connections good, messaging is ok. If i full screen Pidgin and minimize it, the window loads back up as it was minimized, but if i close pidgin (X, not right click and Quit), and open it from the tray, pidgin is really small. just thought this was worth mentioning.
