Flocsy,
I am in-process, working on this as promised; email with details sent to you through the Forum via my own Gmail account. The problem is rather more complex than first seemed and relates to a change in Gmail's accepted mail protocols and our server settings that affects all notifications. Updates ASAP. I appreciate you letting me know about the problem is it is the first notice I received about it.
In the meantime, looking up the member profile as usual and then clicking in their email should invoke your own mail handler to then compose a deliverable message. If it does not (Cc yourself to make sure it is getting through), then a cut-and-paste of the member's email into your mail app will work regardless of mail client...a crude but still somewhat fungible workaround in the meantime.
With best regards, Dan.
