I just downloaded the zip again, the filepost.asp code has indeed been changed now (the JS regex stuff).
I'm confident this will solve that problem then :)

QUESTION:
Why doesn't Cute Editor use a property to set accepted document types ?
e.g. 
    editor1.AcceptedDocTypes = "doc,pdf,xls"
    editor1.AcceptedImageTypes = "jpg,bmp,png"

Wouldn't that be better/simpler in use than having to edit the filepost.asp page ? 

Anyway, thanks for the update.
However, I still have other bug reports from my client, I will start a new thread for those.
