Where is the line between use and abuse?<p>If I install Notepad++ because it allows me to work faster, am I using or abusing the computer?<p>What if I install Firefox because some suppliers&#x27; site doesn&#x27;t work in the company-provided IE8 anymore?<p>What if I install Dell&#x27;s ActiveX control to download their drivers?<p>What if I disable the company-installed Flash Player because I feel safer without it?<p>What if I install NoScript or Flashblock using a company-provided Firefox install?<p>What if I look up my GP&#x27;s phone number using a work computer because I need a consult for my back issues?
