[openbox] Weird bug with NextWindow (ALT+TAB)

[Danko Krajisnik]

I have a weird bug with cycling through windows on the newer versions of 
Openbox. It seems that the ALT+TAB dialog stays open after I release the 
ALT key. I have to hit ENTER for it to disappear. This only happens 
occasionally, not every time I try to cycle windows.

Relevant section of rc.xml:
<keybind key="W-Tab">
   <action name="NextWindow">
     <raise>yes</raise>
     <allDesktops>yes</allDesktops>
   </action>
</keybind>
<keybind key="W-S-Tab">
   <action name="PreviousWindow">
     <raise>yes</raise>
     <allDesktops>yes</allDesktops>
   </action>
</keybind>

My left ALT is mapped to the Windows key with Xmodmap.

Any ideas?
