Hello, First, I want to say that I have no problems with 1.76, it's working perfectly with VP9.2.1. But when I upgrade with 1.77, crashs occured when I exit from VP9. It's not on every table, juste a few one. I suspect VP9 to be not fully compatible with these tables, but 1.76 was working very well them and succeed in closing VP9 properly even if there was an ".net" error. Now with 1.77, when I quit VP9, I have a Windows popup saying : " Vpinball 9.2.1 has stopped to work, Do you want to close ?" Error detail : Application : VPinball.exe Version Framework : v4.0.30319 Description : le processus a été arrêté en raison d'une exception non gérée. Informations sur l'exception : code d'exception c0000005, adresse d'exception 5C6065A4 It seems that 1.77 don't succeed to handle vp9 error. I just came back to 1.76 and the vp error has no more effect on pinballx.
