What version do you use?
It has come to my attention that I am not using the most current version of GIMP thanks to Silvia, one of my readers. Although 2.2.13 is fairly recent(this is the version I use), there is now 2.2.14 which corrects several bugs in the program. And, although I read through the list of "bugs," I didn't see anything that was affecting my scrapping so I decided to stay with 2.2.13 for now.
GIMP, however, has CONSTANT development going on and occasionally a "development" version is released for download. Right now is a current example of this. 2.3.15 and 2.3.16 are both development releases and apparently present a fairly different kind of GIMP to its users.
But for those of you who are new to GIMP, or if you are considering upgrading to the development version 2.3.16, heed this warning from gimp.org:
"GIMP 2.3 Release Notes
This is an unstable development version of the GNU Image Manipulation Program. Please realize that this is just a snapshot of the development tree. We are about halfway up the hill to GIMP 2.4, the next stable release. GIMP 2.3 is in no way a final product. A lot of new features are incomplete and some things may even be completely broken. If you need to get work done, please use the stable version, GIMP 2.2."
You can find more at http://gimp.org/release-notes/gimp-2.3.html but with that kind of warning, I don't want to upgrade yet. I haven't learned to hit the save button often enough in my digi-scrapping yet!
