Brilliant...it won't let me log back in under the previous profile (Kevin_B_Selby) so I had to create a NEW profile. 

this is the same guy...I rebooted the MacBook Pro and tried 10.8.2 (2057) again AND IT STILL HAS VERTICAL BARS ON THE REMOTE WIN10 MACHINE.

So I can confirm that 10.8.2 (2057) has an issue.

I reverted back to 10.8.1 (2048) and the vertical bars on the remote machine are gone.

Oh...and I uninstalled Bing Wallpapers and there was no change in behavior (still got the vertical bars). So I'll REinstall Bing Wallpapers cuz they're pretty.

Went back to 10.8.1 (2048) and reconnected and the vertical bars are gone.

So I SUSPECT it may be 10.8.2 (2057) has an issue. 
I will now reboot the MacBook Pro Intel i5 and try the newer version again...
