The latest version, free version,Qt interface parameter bar keyboard input error.

Sometimes issues like that can occur when your Max user settings are corrupt. Try renaming your

Code:

C:\Users\[YOUR USERNAME]\AppData\Local\Autodesk\3dsMax

folder to

Code:

C:\Users\[YOUR USERNAME]\AppData\Local\Autodesk\3dsMax_backup

And restart Max...then see if the problem persists.

Thank you for your reply , I did it, but the problem has not been solved.
My max version is 2018.
I feel that the problem is still related to the QT interface, 
and there is no such problem if use beta version.
