Find problem v.2B6

There is something weird going on with my find mode (in the select menu).
After selecting FIND it returns after 6 seconds to READY (by itself)according to the status bar info.
If I have a look at the Select>Find command hereafter, this is greyed out! and I have to perform Select>ShowAll.
This happens in all my solutions including CRM.

I am (still) on v.2 Beta6 (Win/FB).

can you try that with RC5 (comming out this week) and if it still happens report it with a sample?
