NIS 2010 virtually stops my computer

Is NIS 2011 (or 2012) much better on "not getting in the way" than my 2010 version?

 

On *so* many occassions NIS 2010 just flat takes-over the computer (when doing LU's) and literally stops any other activity -- for quite long periods (up to several minutes).  Can really be frustrating when you're in the middle of something important.

 

I'm running Win XP SP3 on a 2004 Toshiba laptop.  Only 1.5G of memory.  But, dual-core 3.1 GHz.

 

Tks for any thoughts.
