Hog PC v3.15.1 b3142

Hog PC 
Windows ver 21H1
Win 10 Pro

Anytime i try and alter the print settings within Hog PC it crashes the S/W completely, can't right click or restart and have to restart the machine.
If i try to change any of the print settings this seems to happen.
If i just save the fixture output without any changes that works.
Haven't tested on latest SW version.

Thank you.
