loosing my mouse clicks on a Xoom

 loosing my mouse clicks on a Xoom

Dear all,

I downloaded the pocketcloud few times, install and deinstall them but I don't have a mouse click on the server. Please help!

I use a Xoom with Android 3.01, together with a VPN connection to the company network. I got access to the Microsoft Server 2008 using my username and password in the settings. Later on I see the desktop, I can move the mouse, I can rotate the screen, but it seems the mouse signals will not transferred to the Server. Therefore I can't be sure about function of all the other buttons. Definetelly I can't click an Icon on the desktop screen. I tried many times also the right mouse button.

Anybody here can help? Thanks in advance!
