Firefox compatibility problem - Keybord inactive

Hi,

We are Zoho Business users, we notice a problem with Firefox (latest version 3.01). On certain PC (not all) when somebody try to open a doc, keyboard seen to be inactive and it is impossible to modify anything. In this case, Button on Writer menu bar is always working correctly. We have noticed this problem on Windows and Linux.

I have tried with IE, safari and Opera it is OK.

Are you aware about this problem?

Regards
