nope not changing anything. Its very strange, I can still use alt-rmb and ctr-rmb to zoom etc, so it deffo registers the right mouse button as a click, but when I attempt to hold it to enter a marking menu It will not register and also when I right click a menu Icon I do not get a pop up menu.

contacted autodesk but nothing yet


Edit:
Hmm intrestingly I cannot access the marking menu by holding down spacebar either. Very annoying to say the least
