We have had two jobs that have caused long delays when modifying the drawing.  If you try to sweep an area with the mouse, the csrss.exe file chews up 50+ percent of the CPU memory.  Online I have read this can cause other issues and is related to a known virus.  However, this problem only occurs in the two jobs mentioned.  Anyone else had this problem and if so how was it fixed?  Thanks in advance.
