Using Kaltura All-in-one video pack (most recent version). The window that handles file browsing, upload, and webcam is placed very high on the screen. Only 1/2 of the window is visible. Same results with safari and firefox in both os x and ubuntu 10.10.
Since I'm using kalturace, I sparked up old installations to do more troubleshooting, and wp 2.9.2 and 3.0.1 both worked flawlessly.
