The problem was because we seperate our images and our code. When the dll tried to load all.png it was unable to find it, and somehow ie did "something magical" with the ie cache and it was just wrong. To solve the problem I moved the image into the code repository, and hopefully I won't get yelled at too loudly for putting an image in there...
thanks for your help, the part about all.png let me find it with the help of filemon.
Out of curiosity, any plan to add a grammar check?
