I wrote - quite a while ago - a script to make thumbnails, and modified
it for 2.4.x. When I tried to run it in GIMP 2.6.3, it did work correctly,
but the screen doesn't update as it should.
When the image is scaled, the background doesn't clear, and the scaled
image is shown in the upper left corner. The background isn't 'real',
meaning it doesn't update when something is moved over.
Difficult to put in words. An example is shown here:
The 'hole' in the middle is where the script dialog was. Is there some
extra 'cleanup' necessary in the latest versions?
