Combinig problems

Wanted to combine those parts from radial array and get this message that continue appears endlessly...

Can you send me the scene file?

I have no file scene because I had to close NVil through task manager, that message do not allow to back to NVil and save.
I meat that bug previously it appears when you try to combine some objects, but can not reproduce it.

Just understood why it happens.
Looks like it not releas keys, it keeps run this command again and again like Shift+D is pressed. So I have to press shift or D a lot of times to releas them and stop this.
I thought it becouse keyboard but today I canged keyboard but nothing changed.
I can not reproduce this bug when I save project and restart NVil it deasapears but after a lot of combining that I made to catch it I meat it again.

I have been seeing issues with combine. Today I was doing some scene manangment by combining various objects then renaming in object list(what happened to the lines in object list). But on combining there was screen/UI flickering on tool exit and the object list would disappear.

I just changed shortcuts and bug still here, so changing keyboard and shortcuts do not solve problem.
Looks like it is NVil problem. Keyboard shortcuts are not released and command repeats again and again.
So now I can run this command (Combine) only from UI.
Only I have this?

Also IStonia can you hide this window?

I have removed the dialog.

I just trying to catch that bug but looks like it deasapeared. You made something, or it is because that window?
I made hundreds combining now to catch it but can not find it. May be it will appears later but now looks like everything is ok.
