I made another attempt to load my flight by using SeeYou.
I optimized my flight and hit the 'Submit' button.
I completed the form and was able to enter my takeoff
location as Minden, NV by hand (no drop down menu).
(?why does OLC entry form only allow drop down menu
choices and SeeYou form allows hand entry?)
The *.igc file is downloaded to OLC and I get the following
error message, 'Flight could not be scored. Please
review flight claim, which will open in your browser
for details.'
I hit the 'Show Error' button and am directed to the
OLC-NEWS page, in german. Not flight claim is displayed.

Damn.
