the mouse pointers section states:
Show brush outline, & Show pointer for paint tools
And the pointer mode and pointer rendering? Did you try to change these settings?
What would I change the settings to?
Point mode = show tool pointer
point rendering = show the actual outline of the brush you are currently using.
Like say you have a "star" brush in your brush collection.If you choose that brush it will show the outline of it when you select any of the paint tools.
Most people use the setting you stated above, but sometimes rendering can be very long depending on the size of the chosen brush.
Are you using a tablet?
oh and i need to see an screen shot of the Gimp opened with an available layer created.
I want to see what gets highlighted for availability/use.
