Normally, we execute methods for opening access to the desktop. Unless it is a hidden application, then there is no need for opening access to desktop.
I guess there is some kind of bug, either in Windows 2008 or VMWare or in the combination of those that requires this desktop to be opened.
We rather not call these methods when in hidden mode and we hope that there is a hotfix/windows update to fix this.
We will do some more research but the version you have now should be stable. I guess we will release next version in a two weeks but we need to research some more on this.
Thank you for your patience.
