I've been running tests on this specific anomaly for most of last week. So far, I've tried four different Windows based machines with different versions of Windows and different configurations. At his point, I haven't been able to duplicate the problem, but we're still looking.
Once we can do that, then perhaps we can find out what's common to both your environments or settings that's causing it, so we can perhaps create a fix. May you two guys can contact each other privately and compare notes on what you both have in common from software and hardware points of view?
Thanks for the feedback ..
Regards,
Doug
