I have been using Krita for years and have never encountered this until a few weeks ago, but now, half the time when I use shortcut keys like shift and ctrl and such, it either doesn't act or gets stuck on the selection. It's not my keyboard or tablet physically sticking at all, it's just not registering the shortcut consistently. Any ideas what I can do to get back to smooth shortcuts?

**On further examination it looks like I may have had two shortcuts with the same keys assigned by mistake. I may have been frying the circuitry....! I will let you knw if it's a problem again, but It might be fixed.
