Never seen this before!

Something weird has starting to happen when I visit certain sites.

When I visit certain sites, the Office 2000 installer pops up and asks me for the CD.

I can not find any similarity beetween any of these sites that may be causing this.

Anyone run into this? Should I do a repair of Office?

Which sites produce this behaviour ?

did you check the headers they sent you ?
for instance in .asp you can add a header to instruct IE to instantiate a office app. like:
Response.AddHeader "Content-Disposition", "attachment;filename=filename.xls"
Response.ContentType = "application/vnd.ms-excel"
and when sending <table> stuff it will appear as cells in the browser.

It looks like IE is starting an office app thats not installed and therefore requests the cdrom.

post some of the sites and we can check them out.
