Not so much a Q? as a report...
Got up this AM to discover Windwoes had installed Office and OS update. After the interminable reboot and rebuilding all the work in progress - NOT! first thing to happen was all scripts/functions with READTABLE() failed with internal error.
Reboot "just in case" something didn't get finished updating did not solve the problem.
Regressed that update back out and all returned to being functional again.
