Photoshop Troubleshooting

This is my problem:

I installed some new fonts on my pc, so I open Photoshop, type some text and start going though my list of fonts. The text is changing font faces as I go thorough the list but it doesn't let me go though the entire list of fonts. It will bring me back to the top of my list. If I start in the middle of my list, it works fine for about 15 fonts then it brings me back to my list. I never had this problem before, maybe its the new fonts I installed but im wondering if anyone has had this problem before. If so can you tell me how to fix this issue .

Thanks

I can't say I have had this particular problem, but I would guess it has something to do with the fonts. I'm sure this isnt very helpful, but maybe this post should be moved to a troubleshooting forum.
