Nope, it's a Windows 7 problem, not a Droid/app problem.Win7 32 bit on a Sony laptop that had Vista on it. No issues at all. Easier to modify this Droid than any phone I ever used BitPim for in the last 6-7 years.
You probably have an app installed on your phone that freezes on a USB mount event.
Worst case scenario... get a microSD card adapter and plug that into your laptop. 3 lefts to mke a right, but it will getter done for ya.
