But with each browser, when I click on 'Calendar' in the Menu Row above the opened In box, it won't open the Calendar & I get an 'Error 118, timed out' message.

Prior to the Error 118 message, while it is trying to open the Calendar, at bottom left on the 'Dud' PC it says 'Sending Request"

On all the okay PC's the message at bottom left is: "Waiting for Google.com.' So that is a clue.

Running Zone Alarm on all the PC's.

Have tried changing various Firewall settings, but can't find the cause of the inability to open Calendar.

I don't  think it's a Google issue, I suspect it's a PC set up issue.

Anyone had & solved this one??

Thank you
