In reviewing this I have a theory, the time is so low there is a race condition. Fvwm gets and maybe ignores the release event before fvwm fully processes the push event. Then fvwm gets stuck waiting for a release event, which happens the next time you clicked the mouse button. When using the function wrapper, this wouldn't happen because the function wrapper due to holds, double clicks, etc, would not necessarily we waiting for a release event like the mouse binding might be. Wonder how common it is for the times between clicks and releases to be that low, or if this bug is more an artifact of that hardware or touchpad drivers. jaimos
