I thought of it Joemike, but did not do it because 1) there was no crash/alert box preceding the disconnect, and 2) I am unsure what log to check and where that rascal may be in hiding.
Still, I welcome all suggestions so that I better know the genesis of my ills when/if my problem reoccurs. Indeed I welcome your thoughts.
