I'm a longtime Mac user, but stuck temporarily with a Windows desktop while my Mac is in for repair. It's been ages since I've used Windows! I'm HATING it!
Here is some system detail : Windows XP Pro SP3, IBM Thinkpad, Pentium 1.70 GHz, 512 MB RAM.
Default browser Firefox ver. 3.6.13
Here is my annoying problem : a few days ago I was watching videos on YouTube and Windows?/Firefox? popped up a message that asked if I wanted to install a certain "filter" of some sort. I didn't know what it was about, but I figured it was likely a security issue, so I clicked "Yes." Now, videos won't play in Firefox at all - just get black screen - no audio either.
......now I remember why I hate Microsoft......
