I dont know if the following are ment to be fixed in FP1 but:
Internet Explorer 9 and firefox 4 seem both to have some issues in C10. can anybody verify this?
More specific, in IE9 i cant open a report in report studio, IE stops in initilising during the report studio opening.
And in Firefox4 everything works ok but i cant select a menu in report studio....
thanks

Firefox 4 and IE9 aren't mentioned, probably because they are too recent. I'd take this to mean there is no official support for these.
The 10.1 fix pack may address these, but I suggest you cover the product documentation to confirm this.
