kde 4.3 pager

I'm sure this is pilot error of some sort, but I can't figure it out. I'm running F11, x86_64, fully updated. I use 12 desktops. Until I did the update that brought in KDE 4.3, I had a nice pager widget (not on the panel) with 4 rows and 3 columns, the small images of the desktops filled the widget, and I could adjust the size. With 4.3, KDE seems to insist on a particular shape for the pager--the 12 desktops in this 4x3 configuration take up about half of it and it is not in the same aspect ratio as my display. Also, there's a minimum size it won't let me go below. I created a new user and tried to make a pager with 12 desktops this way and got the same thing, so I *think* it's not something else in my configuration. (If I put a pager on the panel, it doesn't seem to use any extra space, but it's too small for me to use.) How do I get rid of the extra space the pager widget is insisting on using? And why can't I make it smaller? George
