I am using 6915 with WM5, experienced a few times the machine hang up after ex. running HP Photosmart camera, with the error message stating an exception occurred -icm.exe(well known from XP)

the other cases with the same result include changing a profile and running i-Go navi software. The busy icon appears and the 6915 stops responding, the only way to work this out is a soft reset. Can anyone give me an advice how could I solve this, is there any ROM update available on the net or do I need to do anything else? Thanks a lot.
