Review for Provider for Google Calendar by Bernd Prager
Rated 4 out of 5 stars
Great plug-in, very useful.
I do struggle with what seems to be a bug though: Frequently I get a modal window complaining "This item has recently been changed on the server. Submitting your changes will overwrite the changes made on the server". I am offered to submit or discard my changes, but regardless of my choice the error persists. Is anybody else experiencing this?
