Bridge images disappear when I select them

Hi,

I am using the latest version of bridge CC, and when I select an image, it disappears or moves and I cannot find it. Also, if I am down the list of files, it will move me up to the beginning repeatedly.

I have downgraded, reinstalled, restarted, cleared the cache... tried everything I can think of.

I use bridge all day to find files and this is beyond frustrating!

It also freezes quite often.

thanks

Alix
