Hi,
I am testing Affinity Photo 1.8.0, 1.8.2 and 1.8.3 und Windows 10 on three different PCs.
The issue appears with 1.8.2/3 but NOT with 1.8.0 and is very easy to reproduce.
* Start Affinity Photo
* Check "Documents open in a new floating window"
* Open any image
* Create any other layer(s) (for instance an adjustment layer)
* Move any layer (up or down or remove)
* Now Affinity Photo is frozen
Thanks a lot for your help
Cheers
Henning
