Exactly what the title says. I'm using OS X 10.8.2 and GIMP 2.8.2 doesn't seem to have a usable brush editor. The slider bars don't adjust in any way possible, so I'm stuck with the default pre-set brushes…which is highly inconvenient since most of those brushes are useless.
If anyone can give me a guide as to how to adjust the hardness or size of a brush, that would be fantastic. I have GIMP 2.8.2 on Windows 7 and the brush editor works flawlessly.
I downloaded version 2.8.4 on OS X and I have the same exact problem. :(
Never mind, I read the manual.
"The Brush Editor allows you to view the brush parameters of a brush supplied by GIMP, and you can't change them."
Why do they force you to make a manual brush instead of editing a pre-defined one? That's pretty inconvenient if you ask me…
