I’ve had this problem occur many times on every machine I’ve ever used so I don’t think that’s related. The only similarity any of the machines had was that they were all running windows… (win7/win8/win10)
I haven’t been able to find what causes or fixes this problem. But last Friday it did fix itself yet again and as always, i’m curious what fixed it… Could be anything from compiling the lighting to duplicating entities while the alt key is held down, etc…
Is there any file I could send you folks that might be able to diagnose what’s going on? I wonder if I could send you an editor ini file or something next time it happens? Whatever you folks think might be responsible for breaking the alt-4,alt-5,etc hotkeys even after an editor close/restart… The problem has to be saved into some file unless it’s something that could be fixed by rebooting (which i haven’t tried, because if i continue working for a couple of hours the hotkeys usually continue to work again by then for whatever random reason)
