This has happened a couple of times before but normally restarting Photoshop fixes it. Occasionally when right-clicking layers I'll see several of the context menu items/entries duplicated. It doesn't add any more entries, it just replaces some of them (usually the ones I want) with duplicates of others. For example, I want to duplicate this layer but Photoshop is rather insistent that I only create a new layer from the background:
Or in this case, it's really determined that I should set the blending options:
I've previously had situations where 95% of all entries becomes Blending Options, which is not exactly conducive to getting work done.
So my question is, how can I fix this? I've restarted Photoshop but I'm not sure what else to do.
Additionally if anyone has some insight into how this might be happening (it's a rather curious phenomenon) or what might cause it I'd be very interested. I assume Photoshop would load the context menu texts from a localisation file so I can't imagine a situation where entries might end up duped. Could it be a Windows issue perhaps, if it uses native UI rendering for context menus?
