HI Thanks or the reply
Correct if I connect to vcloud or lab manager directly then the mouse of both linux and windows VM's behave as expected. Its only when you connect to a citrix server or through a RDP session that the linux mouse starts to jump. over citrix/rdp, the windows mouse continues to behave normally.
I have also connected to the virtual center server via RDP and opened the VM's in vsphere via a console and the mouse behaves the same , windows great, linux jumps.
Thanks
Mike
