I've been using rEFInd for a few months now and it's been great, so thanks for your work on this.

So far it has been working quite well, but with one exception. I cannot take screen shots. When I press F10, nothing seems to happen. There is no audible or visual indicator (I don't know if there is supposed to be one), and no screenshot file is saved to the ESP.

All of the other keys properly activate their functions (cursor keys, enter, F2, F12). Just in case my F10 button is bad, I tried another keyboard but had no luck there either.

The only other thread I could find in this forum about screenshots not working was due to lack of space. I don't think this is my issue. I have about 160MB free in the ESP, and there is no zero-byte-size BMP file generated as was the case in the other thread.

I'm using the latest rEFInd. Computer is a Mac Pro 5,1. Monitor is a Dell u3415w (3440x1440 via DisplayPort). Graphics card is a PC-based EVGA Nvidia GTX980 with its firmware modified by MacVidCards to support Macs.

The GPU is a bit suspicious to me as the culprit, but as I have no way to test any other video card, I thought I would ask for other ideas here.
