It didn't used to happen but has of late, I type and might have to wait before the letters are showing up, rather annoying. Tips?

I think that I might have solved it, I cleared all cache, cookies, temporary files etc and now can type at my normal speed with the computer keeping up with me. Yay!

I must try that, Sue. Mine has been doing the same thing lately.

Thanks for the idea - I wondered what was happening.

Igot the lag back plus my Firefox kep hanging up and becoming unresponsive towards the evening so I have reset my FF and at the moment it is fine.
