Hello guys,
first of all: many thanks for this great window manager; I've been using it (and only it) for many years now and I just love the configurability. Anyway, it seems I finally managed to find a bug. For some time I thought it was a bug in Eclipse, but now I noticed that using no window manager at all makes the problem disappear, so it seems it's an Fvwm issue after all. Steps to reproduce: Just download any recent version of Eclipse, extract, and start it. Then try dragging a view tab from one place to another inside Eclipse. Fvwm will hang completely, one CPU core running at 100%; I have to switch to a console and kill the Java VM to make things work again. FvwmConsole (if opened beforehand) will display the following error: FvwmConsole version 2.6.5 [fvwm][ComplexFunction]: <<ERROR>> Grab failed in function EWMHActivateWindowFunc, unable to execute immediate action I'm running Fvwm 2.6.5 on kernel 3.12.13-gentoo and xorg-server-1.15.0 at the moment, but the problem has been there for many updates now. I did customize lots of things in my Fvwm configuration, but not the function mentioned in the error above. Since I'm using both Fvwm and Eclipse professionally, I would really appreciate any fixes and/or workaround suggestions. Best regards, Tobias Landes
