After I installed the 19.1 update, I can't go "tab" or use "f" to go to fullscreen mode without losing the right-click menu. Any brush outline that is using a Full Size Brush Tip will disappear as well, if it is over a certain size. I have to "tab" back to the mode where my panels are overlaying my image, and then I can see the right-click menu again. Anyone else have this issue? Thanks! Windows 7, btw.
