Hello Daan,
as always, your replies are greatly appreciated!
>> Has the my.sql settings file changed, in particular the setting about ANSI quotes?
I have the ansi quotes setup in the ODBC system connection. I'd think this overrides anything in the my.sql file; but I will check.
>> Have you tried running ThumbsPlus with full Admin rights?
yes
>> Have you tried to (temporarily!) turn on tracing in Windows' ODBC panel?
I will try this. my recollection is that this creates a very long file that's difficult to understand ;>)
>> In theory TP might be incompatible with your new Mysql version, but I have no details on what goes with which.
this is possible; but I'm doubting it
I'll cycle back after trying these items. any other thoughts, please let me know.
David
