I am preparing a large tutorial on Paint Brushes. My experience is that:
1) The path to personal brushes folders in Preferences>Folders>Brushes is not removed from the system even when the path is removed from the panel and GIMP is uninstalled and reinstalled.
2) Some Photoshop brush sets can cause GIMP (2.6.8 and 2.6.9 on Windows XP) to not open.
Recently, I had a serious problem with GIMP reading an old, test, Personal Brush Folder that contained several Photoshop brush sets. All of the brushes opened in GIMP, worked well, and I opened and closed GIMP several times in the course of testing them. Then I removed the path from the Preferences>Folders>Brushes window. Despite the path being removed, one set from the removed path that caused GIMP to not open. Despite uninstalling GIMP, cleaning out the registry (registry cleaner & manually going through it and remming out any remaining references to GIMP), rebooting, and installing GIMP, that path remained in the start up processes (Process Monitor). Only when I renamed the folder would GIMP start.
What are other people’s experiences with personal folders (brushes, patterns, scripts, etc.) and Photoshop brushes (made in and for PS 6+)?
