I still have problems
I have a Blackberry Tour which worked fine with Vista but no go on Win7 (64bit). I've tried the latest version of Desktop Manager and dropped back to 5.0 and 4.7. No go.
Oddly I had a similar problem with ColorMunki (a device that calibrates your monitors color). A friend suggested running it in compatibility mode and it now works fine. But it doesn't help the Blackberry.
