...when I increase the size of the brush past a certain point and *then* decrease it after use, it turns into an irritating 4 horizontal pip array. I can only make it go away by exiting the program and restarting my machine (the phenomenon continues past closing the Lightroom program proper...so, to get it working properly again I have to restart the machine)...this has a history through previous versions. Anyone know what's up?
