This is driving me nuts so maybe one of you have had this.

I have an Intous4 wacom tablet and use CC photoshop current version. It seems like both have updated recently and I've been having an issue.

I'll be painting, switch over the smudge to push some paint around and for some reason (way to often but not always) the "Mode:" which is typically 'Normal' switches to darken or luminosity or some other garbage. I can't figure out what's causing it because it's not so often that I can repeat it or make it happen. All I can say is I'm angry as a hornet because it keeps screwing up my painting process with bad strokes. The only good thing is it's obvious as soon as it happens and I can undo and go change it back to "Normal" mode. I don't know what it's about but I NEVER use that drop down Mode: thingy on the menu bar so it is ONLY annoying.

I really hope someone knows what's causing this.

My gut says it's a pen thing, or wacom driver, or maybe a Photoshop default setting that got changed when I updated.
