AutoWallpaper and Dual-Core

I recently received an email from an AutoWallpaper user that has a dual-core processor. It would appear that there is a problem with AutoWallpaper when used in a multi-core environment.I am investigating the bug but as I don't have a dual-core system myself it will be difficult to track down. If anyone else out there has tried AutoWallpaper on a dual-core system (XP or Vista) please let me know if you had any difficulties running it.I believe it may be down to the methods used to detect the CPU usage of the system. Please supply the following information: OS, any error messages displayed prior to a crash, processor class (AMD, Intel), CPU usage settngs in AW2.
