Black line around transparent GIF

I am working in GIMP 2.6

I am able to create a transparent gif but when viewing the gif file a black
line shows up around the perimeter of the gif which defeats the purpose of
having it transparent in the first place.

The line shows up around the boundry fo the gif file no matter what canvas
size i make it.

I am sure this is a noob problem and any help will be appreciated.

Tony,

You said "when viewing", but you did not say WHERE / IN WHAT PROGRAM you
are viewing it.

If you are placing this transparent GIF in a web (HTML) page, then the
problem may be that the process of creating the HTML IMAGE tag is
setting the (in HTML) image border to be on by default. One of the HTML
authoring programs has the annoying habit of doing that by default. Set
the border to be off (0) or remove the border information entirely and
you should be okay (if this is the problem).

Also, if your web page is using a CSS file to provide styling, it could
be putting a border on all images, thus you would have to change the CSS
related information on the image tag.

How are you viewing the GIF? Does the outline appear when you use
GIMP's "Filters->Animation->Playback"?

I forgot to mention I was trying to embed the gif file in a video using
Windows Movie Maker.

So, are you sure this is an issue with GIMP, and not Movie Maker? What
happens if you try to embed a different GIF file?
