Subject frmQuery.OnKeyDown: Invalid property value
Author Jens Bo Frederiksen

Just installed the Data Access bundle 4.2Hm in D7. One problem though:

When trying to edit the SQL in an IB-Query (via double-click on the
component or via the inspector) I get the following error message:

'Error reading frmQuery.OnKeyDown: Invalid property value'

and the editor doesn't show.

Any ideas what went wrong or how to circumvent?

(I cannot delete all earlier versions as I have the current customer
releases of my projects in D5 and IBO3x, so I have to keep two
complete installations of Delphi and IB-Objects on the same PC but in
different folders.)
