Krysia I have been using the Virtual Desktop Program by Actual Tools on Win 7 Prof for over a year:
Excellent (easy to use, does what it advertizes, etc) Program - Love It!
From the reviews I have read about this product, most people wrote only one con: "bit pricey" but it does offer over 50 tools for Windows. Most often pro comment: "it works as described PLUS".
Please offer "Actual Window Manager" ASAP!
Thank you, Krys
