Why does my mouse cursor keep flashing?

[D-man505]

The mouse cursor on my laptop keeps flashing between the pointer arrow and the Vista hourglass (pointer arrow with the circle). Why does it keep doing this, and how can I get it to stop. I've been through task manager and everything using a significant amount of memory seems to be normal, except for google chrome. I only have one window with one tab open, and for some reason chrome has four separate tasks running, using almost 200 mb of ram. How can I fix the mouse issue?

that happens to me too. Usually because i have too much info on my computer and i have to remove a few things usually my games.
