Rotating 5D files crashes C1 pro FREQUENTLY!!

Dual 2.5ghz G5, 6gb Ram, OS v10.4.9
C1 Pro version 3.7.4

CR2 images from 5D downloaded to folder, then viewed in C1 pro after shoot to rotate, cc, and develop.

C1 pro crashes frequently when trying to rotate images, wheels of death, C1 chugs and invariably crashes.

Numerous case reports sent to Phase One, also created C1 Case # online (#32515).

Crashes with and without other apps running.

When viewing images, scrolling down the window, C1 constantly has to rebuild thumbnails, is this causing the crash?
