Hi Michael,

Not sure if this info is of any use to you, but ArtCAM had a problem with IE7.
I'm not sure what it was, but they were advising everyone to un-install IE7 until they'd sorted it out.
I think that ArtCAM also uses HTML, so maybe their problem was similar?
Maybe something for you to look at??

Here's a link to the page with this info.

Hope this is of some help, Colin
