Thanks Guys. A bit more info. I have had use of a computer since about 1999, since then I've had 3 different computers
with windows 98, then XP, now 7, & this prob. has occured on all 3 (not same equipment on any 3 systems). I am now on
broadband, with B.T. Just checked speed, 16.7mb download. Surely this can not just be happening to me, others must have
had a similar prob. Remember it does not happen all the time, only about 20% of pictures are affected.
