KDE Desktop pager, can't mouse into app list

[David Little]

I am running latest Kububtu on a toshiba Portege.

When I mouse over a window in desktop preview & pagera window pops up with a 
list of aplications but when I mouse into it to click on the app to bring it 
to the top, the app list window closes.

Can't find anything in system setting etc.

Had the same in Breezy as well.

Where should I look, (no joy with quick google)?

thanks,

david
