Mouse can not work in Solaris 10

Dear friends,

My mouse can not work in my Solaris 10 machine. The mouse itself is OK, i can use it without problems in my colleagues' Unixs.

I outstationed for a few weeks, after came back, it can not work already.

The cursor will float in the centre of my screen and can never move, both left and right click also can not work.

Please advice. ..

David.

Or please advise me where I can configure my hardwares.
