When maximized window of Claws is hidden into notification area and recovered back it shows on wrong coordinates (cca 30,20) instead of 0,0. Seen on versions 3.8.0cvs30 and 3.7.8cvs47.
I an confirm this behaviour in Windows 7 with Claws Mail 3.9.0cvs12
Also with 3.9.3-31-gc98-d95 on 64 bit win 7. It does restore properly from the task bar, just not from systray/notification area
