Usually, when I first start up my system, if I need to use the backspace key or the arrow keys to delete some text or move the cursor, it goes pretty quickly. But it seems that after I've been using the browser for a while, I'll suddenly go to use backspace and find that it's slowed way down. It's not really that big of a problem but it is annoying. Anybody have any idea what could be causing it? I used to have this same problem every time I used Adobe Photodeluxe but I don't even have that installed right now.
