The classic menu itself is not a feature of the tweaker, it’s built into Windows. You can use it without the tweaker too, by holding the shift key while right-clicking. The option just makes Windows think you hold Shift while right clicking. Perhaps you were holding the Shift button when you saw the issue? Does the issue happen when the tweaker is not running?

Please send me an email, I'll try to help you.

It's been a while, but I finally looked at it and I believe that it should be fixed now in v5.8.0.6 beta. Please try it and let me know whether it works for you.

By the way, thank you for the reproduction steps, they helped a lot!

I need more information to be able to reproduce or fix the problem. Please see my other comment in this thread.

Does it happen every time?

Does it happen if you disable all of the tweaker's options?

Does it happen when the tweaker is not running?

Here are previous versions of the tweaker. You said that it started to happen at some point, perhaps the issue was introduced in some version of the tweaker. Knowing which version introduced the problem might help.

Please provide more details, if possible, in English. Attaching a screenshot will help, too.

I've sent you an email. Feel free to contact me if you didn't get it.
