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.
