The problem is that the windows are created larger than your screen. The window height is 2161 pixels but the screen is only 2160 pixels. MinOverlapPercent never places any part outside of the screen. In this case, the algorithm fails and windows are placed at 0 0. The message could be improved a bit in that case; I've obviously missed that case when writing that output. Never happened to me. If you reduce window heigt by a pixel, that should work fine. Personally I'm happy with Style SeaMonkey MaxWindowSize 99 97 which limits the size of Seamonkey windows to 99% of the screen width and 97% of its height. You may want to try that too (or even 100%). > BTW, I'm seeing > > > ,---- > | [fvwm][style_parse_and_set_window_style]: <<ERROR>> Bad style option: > gnomeignorehints > `---- > > > in the log file. Why is this a bad option? The style doesn't exist anymore. Ciao Dominik ^_^ ^_^ -- Dominik Vogt
