It has come to the moderator's attention, that Internet Explorer version 8 has an issue with creating/replying in threads.
The problem normally occurs one attempts to scroll down while highlighting text...the page begin to 'jump' and will not allow one to scroll down while highlighting. I don't know if this issue is only with users who still use Windows XP (which I do and have recreated the problem) or if Windows Vista users have the same problem as well.
Microsoft is pushing this new version of Internet Explorer 8 (aka IE8) to desktops as part of its 'Automatic Updates'...the new version is said to be more secure, but with Microsoft, you have to take that with a grain of salt. But for anyone who wishes to remain as up-to-date as possible (which I do recommend as an IT professional) here are a few alternatives:
Mozilla Firefox:
http://www.mozilla.com/en-US/ (I use this one at home & work...very fast and works well on 99.9% of websites)
Google Chrome:
http://www.google.com/chrome (I also use this one at home & work...very, very fast and works on 90-95% of websites)
You can also do a search for 'web browser' on the internet, but 3 is plenty and these 3 are considered pretty much the best, as far as on Microsoft PCs.
Hope this helps,
