Just a quick post to let you know of a sneaky little problem that only occurs in Internet Explorer. If you ever receive this error :
htmlfile: Unknown runtime error
The problem seems to be that you have multiple form tags within your one page. I stumbled across it because I
had created a user control in the past and didn't remember that it had a form tag in it.
Ok so that is the solution, but to be honest my work around won't work for everyone because I worked out
how to get rid of the form tags, the same might not go for everyone else.
BUT, remember, form tags!!!
Hope this helps,
