I installed the 2.01 Beta version and was using memory caching mode during a session lock. All worked fine until I needed to reboot to exit Returnil's protection. The re-boot took much longer than usual and I eventually got a BSOD. Another re-boot had the same results so I uninstalled Returnil in safe mode. My system: Lenovo T61 Thinkpad Vista HP SP1 Avira Premium DefenseWall 2.46 Vista firewall What other info can I provide to help track this down?
