[Inkscape-user] .png question

Hi folks,

this is my first post to the list after spending a few hours working with inkscape- its great.

My question is:

I created a .png file (which serves as a logo) for a website I'm designing. The problem is, the background appears grey in IE, but white (which is what I want) in Mozilla.

I pretty sure that the background I chose is white in the application itself. Does anyone have an idea as to what could be causing this?

Thanks-

Patrick
