Hi guys, 
  
I'm using AutoCAD 2012 on ASUS WIN 7, i5, 4GB RAM, Intel HD Graphic Card. 
  
For some reason my cursor becomes very laggy and jerky as I use the "Line" tool, 
that being said, my cursor is completely fine when I use any other tool.

I know in the AutoDesk "Knowledge Base" there's a similar Q&A for my situation, but after doing carry out all the AutoCad commands the cursor is still laggy. I don't have a face scanner or virus program turned on. My drivers are updated as well. 
  
  
  
So  far, only "Line", "Polyline", and just about any function that involves  drawing a line (eg: arc), my cursor becomes very laggy. 
  
Any help is greatly appreciated! Thank you! 
  
@ Grant - 
  
No I turned off my Virus program, and have a only AutoCAD running. 
  
Seeing my laggy problem is isolated to "Line" function, I'm thinking my problem is not a hardware/software issue, but more of a setting problem. 
Thank you for your reply though Grant!
