My guess is that vmware grabs all mouse events when the pointer
enters its window. I am sure there *is* a vmware bug since it
should release the grab when the pointer leaves its window, since
you seems to have set it up to behave this way.
About focus not being transferred outside the vmware window: when
the pointer is (un)grabbed, X generates EnterNotify and
LeaveNotify for the windows involved. It is important to ignore
some of these events. For example, if you have something like
mouse 1 a csm Next (xterm) Focus
You would not want that the EnterNotify for the window under the
pointer that is generated when the automatic pointer grab is
released makes fvwm focus the window that already had the focus.
There are delicate heuristics in fvwm that try to guess which have
to be ignored and which do not. But there is no way to make it
work hundred percent reliably.
