computer slow down while playing

does anybody else experience the computer slowing down while playing so much so that you can't hardly move the cursor and you end up losing.   

Sounds like a memory leak.

What version of software are you using?

Windows? Windows WHAT? XP is no longer supported, and no longer receives updates.

Internet Explorer (which version?) or Firefox?

Do you have Automatic Updates turned on? Is it actually up-to-date, or just downloaded and pending?

Is your Java up-to-date? Anti-virus software?

Yep, same probelm here (Win7 64, FF 31), automatic updates on, clearing cache, etc. nothing helps. Only scripts I have allowed are from chess.com and chesscomfiles.com. Even in "private window" the same problem.

But it seems with IE everything works fine now.

Google chrome disabled java use. Try a different browser. 

Might be obsolete drivers...
