Driver_irql_not_less_or_equal

[lubor]

Hi,
I have the "blue screen" with DRIVER_IRQL_NOT_LESS_OR_EQUAL and:
STOP: 0x000000D1 (0x82200000, 0x00000002, 0x00000001, 0xA8F265B7)

This always happen when sending an e-mail from Outlook.
I have recently installed a WiFi USB stick - NETGEAR WG111FS - can it be related?

Thanks a lot for your help!
