Thanks for the assist. xplorer just keeps posting those smug and sarcastic posts, which may boost his own eqo and sense of expertise, but I just find him to be annoying and useless. By way of some personal background, I have a PhD in Physics from UC Berkeley, worked in high tech here in SI valley for more years than I would like to admit. Paid to hunt down and resolve impossibly difficult technical issues in technical R&D. Patents, publications, talks, the whole bit. I've seen all kinds of "technical guys", some competent and some like explorer, who needs to show everyone how smart they are by taking shots at those around them. xplorer seems especially fixated on doing this, distorting my posts, pointing out all the vital details I left out, other excuses why he couldn't offer up a simple answer based on the information presented, u.s.w. I no longer find the need to respond to him, much less look at his posts in the hope of finding anything of use. In that regard, I won't be responding to his next salvo, sure to follow forthwith.
For the rest of you guys - thanks for the inputs. I'm sure you realize your answers to me are primarily a vehicle to extend the understanding of the other forum members following this thread, who may find themselves facing a similar situation with their downloaded apps.
And for those of you who may be reluctant to post your questions here - don't let my experience with this overly sarcastic "expert" prevent you from posting your questions - guys like him are in the extreme minority, serve no useful purpose, and are best ignored. The rest of us are actually here to help each other.
