How to fix mouse cursor and key cursor lag

Another noob question. I'm switching over from Vista so still trying to get used to snow leopard.

Couple of things that are bugging me:

1) The trackpad seems to lag slightly when I select text or re-position windows on the screen.

What I mean is that when I double click and drag to select some text for example, when I lift my finger from the trackpad (which should end the select procedure) and move the cursor elsewhere, text selection still happens.

The only way around this is to not touch the trackpad for about a second before I can move the mouse cursor elsewhere.

Is there a way to get rid of this 1 second lag?


2) When I'm typing, and want to move the key cursor over my text, when holding down the arrow keys, the cursor still moves over text very slowly.

Is there a way to speed this up?

Thanks.

 

No one??

I would really appreciate some input on this
