My friend is using protobot and every time he uses the transform mode to move parts they duplicate as if he was clicking alt. Has this happened to anyone else? How can he fix it?
Is their alt key sticky? Maybe go to preferences and see if you can turn it off.
This used to happen to me, but it was a while ago. I think I used to exit protobot sometimes and other times I would delete the item in question and clone it again.
We fixed the issue, thanks for trying to help though!
We deleted all protobot files and redownloaded it, in case any one needs this
it started again if you have any other ideas please post them
What sort of device is it? Have you ever had other keyboard issues? If you hit the alt key does it reverse the duplication glitch? Just trying to help!
we are using windows 11 laptops. we havent had any other issues and it does not reverse it. i found the solution though
the solution was to change the keybind for duplicate. i changed mine to alt + v, he changed his to alt + d
Awesome! Glad you got it figured out 
Sorry for the late response but I’m pretty sure it happens because when you alt-tab to another window then back to Protobot, it will believe the alt key is still held down.
Re-binding the key is one solution, the other solution is just to tap alt again whenever you switch from another window back into Protobot to “reset” it. Hope that helps for anyone else reading the thread
