Hi ~d,<br><br>Thanks for trying to reproduce my results, I really appreciate it! <br><br><blockquote style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex" class="gmail_quote">Oh, are you running mplayer in virtualbox? Can you reproduce this 
problem when running mplayer in xmonad directly? Is xmonad running on 
the guest or the host (or both)?<br></blockquote><div><br>I realize now that I was unclear, sorry about that - no, mplayer and virtualbox are two separate examples, I run mplayer directly (and let xmonad handle the window). Same with virtualbox, xmonad is running on the host and the guest OS is Windows XP.<br>

2. More detailed reproduce steps:<br>
- Run &quot;mplayer /path/to/video/file&quot; in a terminal on [screen 1]. A floating<br>
mplayer window should show up on [screen 1].<br>
- Press &quot;f&quot; key to make mplayer fullscreen.<br>
</blockquote><br>
Nothing happens after this step! Perhaps we&#39;re playing with different versions of mplayer?</blockquote><div><br>What do you mean with &quot;nothing happens&quot;? Doesn&#39;t mplayer fullscreen work at all? Can you get e.g. VLC to do fullscreen? I have the same problem there. I can also reproduce it with flashplayer, but that one&#39;s a bit different since by default Flash will exit fullscreen when it loses focus.<br>

<br>With best regards,<br>Hans<br></div></div>
