It's gotta be a software, not hardware issue, most likely dealing with your drivers. I'd check Device Manager and see if any flags (yellow caution symbols) are going off for the mouse driver. If the mouse is beyond the basic two button mouse, try reinstalling the software that came with it. If you are using custom cursors, try switching back to the standards for a while. Also, check Task Manager and see if any odd processes are showing up. The exact instructions and what you're looking for depend on your operating system and model of mouse, so make sure you include that in your response.
Let us know.

P.S. The good news is that this is not all that uncommon and is rarely a hardware issue, so it's a matter of debugging, not spending money to replace parts.
Recently my mouse curser started freezing. Everything with my computer is fine and i can even continue to use my mouse as long as i can guess where the curser is. It is pretty annoying and only seems to happen with a few applications open.
Could someone tell me if this is a Hard Drive problem? Memory Problem? I dont think its my mouse. Virus? Im stumped because i have never heard of this happening before. Thanks for any help.
Im running 2500+ Athlon system with a stick of 512 pc3200 memory. I have two 60 gb hard drives aswell. If more specs are needed let me know.
Thanks!
