C1 3.6 LE Problem (I think)

Hello,

I've been a long time c1 user on the PC, just switched to os x.

Machine is a dual 2.5 G5, 2.5g ram, 2 250gb sata's.

Loaded about 30 images into a folder, got the thumbnails, and I can click on a thumbnail and the image preview seems to come up fine.

I'm using a Wacom Intuos 2 graphics pad with the supplied mouse (2 buttons and a scroll wheel)

On the thumbnails when I scroll down (image is in portrait orientation) they scroll just fine. As I scroll to the next thumbnail the appropriate preview appears.

But if I go to the bottom of the list of thumbnails and scroll up, the thumbnails go bad. Here is a screen shot of what it looks like

If I then click on this mess of thumbnails, they will all appear correctly and one will be highlighted.

I am able to scroll up and down through them fine using the arrow keys. This only seems to happen with the scroll wheel, and only going up.

Mouse seems to work fine in all other aspects in every other program I have tried it in.

Since I'm new to Mac's this might me my fault and not C1's - Anything I should adjust or check? Or just wait for 3.6.2?

thanks,
