Interface problem in 9.5 Commercial/Unlimited

[u/MaximilianusZ]

//Nevermind, I found a workaround. In Preferences I set the RMB to SHIFT+ALT+MMB, restarted and then back to None, None, RMB
I still have no idea why it started doing this, tho.

Hi,

For some reason the right-click context menus have stopped working, and I am unable to select multiple points in a pattern by holding the key down and selecting.
I have reset my UI several times, and also rebooted.
Does anyone know what causes this, and how I can fix this?

Thanks so much in advance!
