I retested everything this afternoon and received the exact same results as at first. I ran a virus scan just to be sure and all detections=null. I’ve picked up another copy of v3.1.0 and will roll back to that very stable version just like you have, kingtubby, in a few minutes.
I found 3.1.1 beta2 to have no issues, so whether I’ll return to running that EXE over the top of 3.10 or not I can’t say. I may simply wait for needed fixes to the alpha. I see other issues with the latest showing up on the forum, so I suggest sticking with 3.1.0 until we hear more. Cheers!
