Click and hold on the title bar and drag the window to such a place that you can see one of its corners. Then click and holdone of the corners and resize the window to a size that's more convenient for your video display.
Let me know if this helps.
All I can suggest, then, is a window management emulation bug in VMWare on HP.
Is this happening with any other application windows within the VMWare-hosted environment, or only with your IPVanish program window? Any program with standard window manager decorations should be resizable, minimizable, maximizable in the standard fashion.
Yes, the IPVanish program may have programmatically disabled the actions associated with the window manager decorations (maximize, minimize, resize).
This is a very irresponsible thing for a program to do. However, it is not only legal, but quite straightforwardly accomplished.
Why on this platform but not on another--who can say.
You are welcome to try as many other sources as you like. The fact is, the behavior is only explainable if the software deliberately overrides the default methods associated with the window manager decorations. Sorry. Why that would be the case is anyone's guess.
Bear in mind that being an expert means possessing sufficiently profound understanding to be able to figure out what's going on. It does not necessarily mean having encountered every version of every package on every host O/S. The fact is, if you continue to run the same application from the same vendor within the same virtualized environment on the same platform, the same results WILL be evidenced.
