The Weird and Wonderful world of Computers.
I don't think,(but may have somewhere in the distant past), that I made a tweak to change the Save As.
And how it knows, ....(well, the Shadow knows).
I didn't play any further, since I really wanted it to remember where I saved last, as opposed to changing the location of My Pictures.
One of the fields that showed as a Not Found was HKCU\....\CV\Explorer\User Shell\My Pictures. So my "guess" would be that perhaps setting "My Pictures" to a folder may allow it to be offered as a default.
It's one of those, would be nice if it worked, but not so painful if it doesn't work, tweaks!!
Now if I could just turn off Modemlog (again), I'd be laughin'.
But that's another story, and perhaps post, when I surrender.
