I thought I'd pass this along in the event that anyone experiences problems:
GIMP 2.6
Installed from Spin 201109
When saaving a picture as a different type, the "+" doesn't work (to change the file type and extension).
You will need to actually click on the "Select File Type (By Extension)" to open up the available file types.
Beyond that, the saving process works as it should.
