Linking to Safari from Calendar, Mail, Messages, Notes, etc suddenly broken
Within the last day or two, attempting to click on a URL in applications such as Calendar, Mail, Messages, and Notes fails to open the corresponding page in Safari. If I copy the URL, open a new tab in Safari, and then paste the URL into that new tab, it does work. In some cases, the click simply shifts the focus to Safari and does nothing else. In other cases, I get an error message from Catalina. Examples include:
"The application "Safari" is not open anymore."
"The application "%@" is not open anymore."
In both of those cases, Safari was open and running at the time.
All of this worked perfectly for several years, until a day or two ago.
Last, I just tried this on an identically configured "sister" iMac to the one I normally use, and clicking on URLs works perfectly. So, I suspect some sort of Catalina or Safari setting got corrupted.
TIA for any ideas,
