Window update problem, when set for maximized windows only

I guess, it relates to issue #33, or there is same wider problem in both cases.
This problem affects both plugins - for title+menu and buttons as well.

I'm using it with compiz, and difference is visible when using Scale plugin.
If configured for all active windows, plugins update active window, when some window is hovered is scale mode.
But if configured for maximized only, this update happens only on second "Scale" attempt (just after activation, even before i hover some window with mouse).

For buttons it is visible, when wrong window is closed.

It is hard to detect in other modes... when switching windows by Alt+Tab, everything is OK.
It doesn't seem to be compiz problem, because window buttons and window menu applets are OK in this situation.
