It should be able to run fine with OpenGL 1.x just go under Settings and make sure OpenGL is set to 1.x. Then go back and re-read my last 3 posts. There have been several things I've suggested that you did not let me know if you tried.
Computer is a
Dell Optiplex 755 desktop running windows 7 32 bit
Went to the Zoom Download & downloaded clicked join audio & because I do not have a microphone could not figure out what I was suppose to do. Closed & then went to FB which I DO NOT DO but signed up anyway & was just approved to join. So now we will see what happens.
I still think it is a setting in the program my computer does not like causing the problem. I went all the way back to ver 35 & tested it & still locking up when effects are changed.
For now I have given up on the text till I can figure out if my computer will ever work with xLights. What I have been able to do with xLights is so much easier then LOR not to say way cheaper even with a donation.
