> Thanks. Can you send me a description of how to reproduce such an error? Reproducible every time: start with windows A, B, C, D, E stack windows ABC snap window D to left side of ABC stack E to D move E away from ABCD stack B to D stack C to D. I'll send the logs if you won't be able to reproduce it. Random thoughts: when stacking too many windows, the tabs of some of them get under the tabs of other windows and disappear; I guess the tabs could be shrunk with part of the text replaced with an ellipsis, so that all the tabs are visible at once; sometimes when I move two tiled windows to a place where a third window X is, the active window is above X, but the tiled window is under X; when unstacking windows, the position of the tab doesn't change so you get windows with tabs not in the left corner but moved to the right. I guess if the tabs would return to the left it'd be prettier. the diagnostic messages that get into /var/log/syslog are garbled because debug_printf("HE"); debug_printf("LLO"); results in KERN: HEKERN: LLO HTH, Adrian. -- Czy ty orzeł, czy ty kawka? -wkrótce zdłabi kaszel, czkawka.
