Blender v. 2.78c
Short description of error
On this graphics tablet I assigned SHIFT to one of the hotkeys and unfortunately nothing happens when pressing this hotkey, such as pressing it with the middle mouse button to pan the view. The tablet has 8 hotkeys and I even assigned it to a different ones with no luck. I've assigned CNTRL, ALT, SPACE, TAB, & even combinations of these keys to the hotkeys and they all work except for the SHIFT hotkey. However, SHIFT does indeed work on my laptop's keyboard, just not on the tablet. I've even tried it with a different version of Blender, the recent Blender shadow catcher build, and it still will not work. Restarting my PC didn't help, nor did disabling all of my add-ons. What leads me to think this may be an issue with Blender is that the hotkeys, even the SHIFT hotkey, DO work in other programs, just not in Blender. I even contacted XP-Pen customer service and they were able to successfully use the SHIFT hotkey with the same tablet in the Blender v. 2.78c, and they also suggested that this may be a Blender issue. The funny thing is that I do recall this button working before, and the only thing that comes to mind that might have caused some conflict is that I updated my NVIDIA graphics card drivers. Have you ever heard of graphics card driver updates affecting tablet functionality? Has anyone else had issues with their tablets, Wacom or any other brands, with Blender?
Exact steps for others to reproduce the error
I know this error is impossible to duplicate unless you own or have access to the same tablet, but I was hoping you could give some insight as to what may have caused this issue. Thank you for your time.
