So, just as a check, if you go into your Work Environment and look at the keyboard shortcut for Drag a Copy, does it show it using the SHIFT key?
I am sure that it will.
There may not be an uninstaller program for Archicad, but there may be something in your operating system.
In Windows we have a add/remove programs option that we can use.
Sorry, I have no idea with Macs, but is there something similar?
Just deleting the program will work but you should also delete all of the Graphisoft - Archicad 10 folders in the user preferences as well.
You may need to do this even if you uninstall the program as the can be left behind.
I am not sure though that re-installing will solve the problem.
You mentioned in your first post it was working before.
Again I know nothing about Macs, but is it possible to roll back your operating system to when it was working properly?
I recall some other posts here with the same problem.
It is just a matter of being able to find them.
I will see if I can.
