You can send me an email, yes, but the software is not stuck. If I click on tab on the top like "file" or "Shader" I see the sub menu appearing and disappering really fast. But if I click on an option on the right like "adjustements" "dithering" or ReSampling for exemple, I see the sub option, but if I click on "On" it's like an infinite loop which switch alternatively on/off... I have to click again on the upper menu option to break the loop :

I tried to find softwares I had this similar problem, but I can't, it was at the begining of the last year, and I don't remember which exactly, I tried some of them just now but it's look working fine... But I know I had exactly the same issue with one or two others.
I have the last version of the nvidia driver installed (461.09)
