Yes it is what I want to do, but it just won't happen. The calendar in question was set up when I discovered Google calendar just as something to experiment with. Then came the extra two calendars which work fine. But when I try to delete the first one I get the following msg:
You are about to permanently delete all events on your primary calendar.
Once deleted, events cannot be restored.
Are you sure you want to delete all events?
Yes please says I, but when I reselect Google Calendar there it is still there in all it's glory. I assume it is my primary calendar because it was the first one installed, but there is nothing on it I want.
