[DV4mini] dv_serial.exe has stopped working

I'm experiencing the following issue where Windows 7(x86) is reporting that the "dv_serial.exe has stopped working" after a period of working just fine for days.

In order to correct the problem, I find that I have to uninstall the com port (usually com3) in Device Manager and "Scan for Hardware Changes"
I can then reload the DV4mini control panel, and it works once again for an indeterminate period of time.

Is anyone else having the dvserial.exe crash on them?
