I thinapped an application that includes a drawing component. When the application is launched on a Windows 7 machine and you try to draw a line or any other shape, the application is leaving behind ghost images of the line or shape as you resize it. The problem is only happening in Windows 7. If I open the same application under XP, I do not have the issue.
I used Thinapp 4.7.3 to create the virtualized application on a Windows XP base.
