Part of Jeff Attwood's answer to this problem back on Dec 24 10 was
I do not have that entry in my registry. When I search the registry for .html, the first result is
(value not set) Next result is
HKEY_LOCAL_MACHINE\SOFTWARE\Classes\.html (Default) Opera.HTML
There are reference's to Opera throughout the registry. I have never installed Opera on this machine.
IE is Ver8 which seems to have some problems. deleting browsing history either locks up machine or stalls for a long time. upgrading to ver9 didn't solve the problem, so went back to Ver8. Normally would not use IE.
Avant 2010 build 130 is my default, I know it uses the IE core.
Mozilla 4 is installed
System is Dell Latitude E6410 4 Gigs Win 7 Pro. Win XP Mode
Interestingly there is no reference to Opera in the XP Mode registry. Nor does deleting temp files slow the machine. Hyperlinking works in XP Mode Word 97
All I want to do is use hyperlinking in Word 2007 without that message Any suggestions would be appreciated. Most posts elsewhere refer to hyperlinking in browser or Outlook which I don't use.
