For whatever reason, when I'm in the terminal or Dosbox, if I hold the left shoulder and hit E, I'm locked out of all input except for moving the mouse and the logo key; all keyboard input, clicks, and touchscreen are disabled until I do a hard reset. I've tried doing this in some other apps, but nothing else seems to cause it to lock up, and I've never noticed this before. Even recently, I was able to do it in Dosbox with no problem. It only just started happening today, and it's consistent; I've tried it several times with each app. Given that it only seems to effect these two apps, I think it's a software problem, but I have no idea why it would ever do this. Could there maybe be a short in it somewhere causing it to simultaneously use some other E-key shortcut? I'm really at a loss with this one. --- Double Post Merged, Apr 9, 2017, Original Post Date: Apr 9, 2017 --- Update, I just tried Dosbox again, and this time, I didn't need to hold shift. It seems to be happening randomly now.
