Hi all, greetings from the Wine booth at LinuxTag! :) (Uwe Bonnes and me are there) The following program which a school employee (4000 pupils!) asked me about that prevents his school administration from switching to Linux has problems with continuous redrawing of the menu bar and non-redrawing of the client area (resulting from continuous menu redrawing?): http://schulverwaltungsprogramme.mswwf.nrw.de/mswf_software/html/winplan.htm... Note that installation runs fine; it's the main program which breaks. The relay log shows signs of a WM_WINDOWPOSCHANGING/WM_WINDOWPOSCHANGED loop or something like that. If someone more familiar with messaging and window management could have a look at it, then I'm sure he'd greatly appreciate it. :) Greetings, Andreas Mohr
