Aethec - I tried MSIE 8 but it doesn't offer the same Links control as MSIE 7( and I have a L-O-T of links !!), so I went back to v7...
I mainly use MSIE for browsing, but use MSIE,Opera and Mozilla for testing. Same issue with all of them.
Manually viewing the website source code shows it HAS been updated.
CCleaner is configured to delete everything except specific cookies, and nothing from my website is selected to be saved(which would at most only be a cookie, and I don't need them), so that should be sufficient!
I think the question is : What is Ctrl-F5 doing as far as any MSIE cache is concerned ?
