Open the gif in Gimp and check that you have transparency
It is probably the 'tool' you are using to view the gif I use linux so I do not have those you referenced
exanple: nview on the left does not show transparency (shows white) Same image and viewnior on right does.
Some web browsers can be the same, Firefox shows white, Slimjet shows a checker pattern.
