Hi, I am using Parallels 12 a MacBook Pro that is docked and running through my Thunderbolt display. I have one program that is giving me a runtime error when I use it, but when I disconnect the monitor and just run it through the laptop display, I get no errors when I relaunch. This program is PC only and therefore the only reason I run Parallels, and I get no errors due to the display connection for anything else on my computer. Anyone have similar issues?
