When using the adjustment brush it will quit working and begin erasing the adjustment even though brush A or B is selected. Adjusting the flow and density sliders makes no difference except for the rate in which the brush erases. Was not having any issues till my Windows computer did an update that didn't go smoothly, which locked up my computer. I have uninstalled and reinstalled LRCC, but it has not changed the issue. Currently the only work around I have is to open a new adjustment brush and it will work for a short while.
