From v184.108.40.206 I've started to encounter strange behavior (long delays, read errors, etc) from drives that are not a selected drive in the AnyDVD settings. Up to and including v220.127.116.11 was never any problem. I've attached a shot of drive selection settings that shows only some of my optical drives are selected to be processed by AnyDVD. However, now, if I try to perform two separate processes (one with an AnyDVD drive and something else on a non-AnyDVD drive) at the same time, they seem to stumble. It's not specific to any particular DVDs or Blu-rays, just in general. As before, never any problem before updating to 18.104.22.168.
