Hi Mike,
Firstly like others congrats on 20 years, Seems like i've used it forever but the oldest installer i have archived is q08-205

Love the UI update

Now for what is to me a MAJOR pain (bug) in the backside. QU does not initially remember which monitor it was last used on and always starts the splash screen on monitor 1 and then throws a monitor profile error..... once you get rid of the dialogs the main UI then opens up on the expected screen.

This also occurs in 2017 version as well but i've only just gone over to a new photo edit setup with a large 55" screen and hence screens with different profiles.

I hope that makes sense.
cheers
Phil
