I have now put the dll in every imaginable folder just to be absolutely sure that is not the problem, and it did not help.
Another funny thing is that my CuteEditor looks like this in IE:
But like this in FireFox:
However, you can't enter text at all using firefox, most things are disabled.
A third interesting thing is that when i remove the CuteEditor.dll from the location it was originally, the page won't load at all. So I am rather sure the application has found, and use, the right dll the whole time.
