This happens to me every now and then. The painting cursor in
PS would suddenly change from brush size to a cross. Result, I couldn't figure out if brush size is too large for the area I'm fixing.
The painting cursor setting in Display&Cursor preferences is still set at "brush size."
Closing
PS and running it again won't correct the problem, but if I reboot the system, the painting cursor would turn back to brush size again.
Is there another way of fixing this problem without rebooting the system? Thanks.
