The information you found is correct. Alt+Tab crashes the client on some systems. It works fine for me on Windows 8 though. Alternatively you can install Team Viewer and leave it running in the background. This seems to fix it for most systems. For more details see this post.

This is slowly going off-topic though. So if you should have any further questions regarding something not strictly related to Devianne, please make a new topic in the help section.
