Hi everyone,
I'm running Aperture 3.4.3 on a MacBookPro with all the latest updates. I'm having a problem I can't resolve after checking all the view and window menu. My photos are all going to the right, instead of fitting in the Main window area.

In browser mode, they go on one line forever, instead of fitting all in the window in blocks. In split view and viewer I can only see a small part of the image which is hidden. I can see the image when i stretch my window on two screens wide.

What is strange is that verything is working fine in full screen mode. I've searched all over and finally found this site. Anyone's help would be greatly appreciated.
Charles
