FYI for Support: After having problems with 4.6.5 accessing a network drive, I downloaded the Beta 4.6.6 and had no problems with it, but it expired. I then tried 4.6.6.2, but started having problems with it hanging up again with 'not responding' when accessing that drive. Today I downloaded 4.6.6.3, it seems a bit better than '2', but I still ended up with it not responding a few times. I'll work it some more tomorrow and see how it goes.
