[Dave Matthews]

Thank you for that verification Fabiano!

I have set the refresh time to 10 seconds and encountered the same F1 
problem.  (My apologies to everyone for the screw-ups I made on AO-51 
half an hour ago, part of the F1 delay problem!  I won't try that again.)

Your English is fine Fabiano, and you have been a great help to me. 
Thank you very much!  If I find out any fix I will let you know.

73, Dave KI4PSR
