Thanks for the response Deacon, I also expected the Netbook to perform as it does, but the spec of the Netbook isn't relevant to the issue as it is a pup in comparison to the HP Probook that has the issue. I just entered its details to show that a Netbook works ok, yet the Probook with the same software platform doesn't.
The probook has 4gb main mem, dual proc (2.4ghz) and a Windows rating of 4.5, so should "eat" the application.
