Several times a day while in Windows, some of the keyboard letters start issuing windows commands. Like "letter d" launches "Show Windows Desktop". kinda annoying when you are trying to write emails! Unloading and reloading the keyboard in Parallels doesn't solve the problem. The only way to clear this up is to shutdown the VM and restart. This is getting beyond ridiculous! Also, I thought version 5 was out & recently installed, but when I select "check for updates", I get the message that I have the latest version of Parallels installed.
