Hi -- I'm new to ImgBurn, so I have do not have a version history to compare your latest with. I'm running Vista Business SP2 32-bit, and found myself uninstalling the product once it was installed. I don't recall why, but I was intent on right-clicking either ImgBurn or its shortcut, to view information displayed under Properties. Each time I clicked on Properties, the display "blinked"-black, returned and never allowed me to view Properties. I wasn't comfortable having it installed at that point.
I'm not about to disappear as quickly as I uninstalled your product, though...
