Yeah, I'm a Linux guy and the old version ran fine on XP in VirtualBox but that stopped with the new version. So I dug a Windows7 laptop out of the closet and hooked it up to one of my monitors. It has been working just fine except the lappy only does 1600x900 resolution. No big deal until today's update broke everything. Then I thought, 'what would Windows guy do?'. Oh yeah, re-boot. Well it actually ran for a while after that and then it crashed without warning in the middle of a game. I don't need the aggravation, so I'm giving up. You win for now, hope you enjoy your Christmas.
Coincidentally, I ordered a Windows 10 Mini PC the other day (5"x5"x2") and it should arrive Thursday. Mostly I did it out of curiosity about how the Dark Side lives, but maybe I had a premonition this was coming as SwC Poker is the ONLY thing I actually do on Windows. What the hell, even with a SATA SSD it was only about $250.
