Hey, #GIMP using friends: I have either discovered a bug, or I am fatfingering myself into a mode over and over again.

Every time I switch to a selection tool (oval, rectangle, lasso), I somehow end up in SUBTRACT mode, and have to mouse over to the tool options panel and click the "Replace" button.

I have never, ever consciously switched this tool to subtract mode, which leads me to suspect that I am fatfingering it back into this mode somehow.
