I missed this part :-(
"Steam expected to release early next week."
probably why steam WAS still working correctly, no longer... :-(
after spending a few hours AGAIN on this I have got the window sizing where I like it w/o borders. Have not been able to solve the dots on the grid lines tho, they blink on and off at regular intervals. If one could figure out the patern of the blinking I am sure it could be used to count dot speeds. Problem is they are not clear enough for my bad eyes.
for the resizer, I figured out if after you launch golf under options switch from windowed to full screen. When it asks to keep changes or revert if you select revert then resize the window w/o the goofey borders. I did have to adjust the resizer as the windows were NOT the same as pre update.
