Keep getting a message "swShellFileLauncher" error

I'm not certain what this message is implying, but I get it a handfull of times during the day. The error "title" is not found in the search of this forum so I posted here.

Am I doing something that causes the need for this flag? I'm working along & notice "2" SW icons in my tool tray and when I look at the second, this is it. I close it and continue along as though nothing happened. Strange.

Thanks.
