I have a custom query, probably I have had it some time without every using it.
I have tried to run this query but get the error message that it is not a valid FH query.
It is showing in the list of queries but when I try to delete it by the following To
delete a Custom Query use View > Custom Queries > Delete Custom Query, select the
Query name, and click the Delete button. I get the message "an error has occurred ,
One or more deletions failed" and the query is not deleted,
I eventually found the offending query in C: program data \Family Historian and deleted
it. There does seem to be something wrong which prevents, probably obsolete queries, from
being deleted through the normal methods.
