BUG: focus lost when transitioning to another file in FS

[beholder4096]

Build 825 v. 1.36, WinXP SP2, playing in internal renderer overlay (default), settings:
movie settings NOT remembered
last movie position remembered
pan scan and movie window size remembered
last movie position remembered

If you have repeat all option on and play short AVIs in fullscreen, the player plays a short AVI file fine for first one or two times (as it repeats it).
THEN the BSplayer "application focus" is lost when transitioning to play it again. The bottom pane of WinXP appears on the bottom of the screen (see attached pic -- I had to fake it, since it's quite difficult to shot screens in overlay). The mouse may also appear AND DOESN'T DISAPPEAR. It looks a bit like desktop mode, except it's a bug, not a desktop mode.

This same problems happens when transitioning in fullscreen between two CD1 and CD2 movie files.

This bug is present in the last few versions. It was not there before, the AVIs were transitioning ok.
