I'm having a strange problem with the Windows XP machine of one of our developers after having installed .NET 3.5 SP1 (at least, the behaviour wasn't apparent before this point).
After installation, neither Firefox nor IE would display any CSS, but Chrome would. Using Firebug under FF, the CSS was being downloaded & read by the browser, just not applied. Any manual CSS changes made through Firebug wouldn't appear either.
Now I've noticed that the problem occurs with .CHM files too, which makes sense given its reliance on the same underlying libs as IE. This seems to imply that Firefox is using one or more of the same components that IE does for handling CSS (but that Chrome isn't)?
- removing & reinstalling Firefox
- installing IE8
- removing & reinstalling the .NET SP update
- reverting to an earlier system restore point
None of which has made any difference whatsoever.
Any suggestions would be greatly appreciated.
