Problems with 12.6

I have had more problems trying to run 12.6 than any earlier version of Opus. Although I will say that Opus 10 started crashing often and so that is why I bought 12. using Win 10 Pro 64 bit. Specifically:

  1. Way too slow. I find myself starting Opus 12.6 and then waiting, so I start File Explorer, use it and am done with my operation before Opuse is even ready.
  2. Unplugging my iPhone does not remove it from the tree. I get numerous messages that the device does not exist and I have to go through each one before it lets me click on another folder.
  3. Random hanging/crashing.
  4. Moving files from my iPhone to disk sometimes crashes Opus so I use File Explorer instead

For 1 & 3 at least:
