Hello.
We have a little problem using a ULCRegularExpressionDataType for
validating the user input in tables. When trying to integrate the datatype
as cell editor for a table and starting the application with speakers
turned on, you hear the warning audio sound from Windows (XP). When
scrolling down the sound appears multiple for each table row. This
behaviour only seems to come up the first time a row is "loaded". Please
see the snipped below to rebuild the situation. We use ULC version 6.1.1
and the default sound configuration for Windows XP.
May be we are integrating the datatype the wrong way, so we will be glad,
if you have any hint or idea to solve this problem.
Best regards,
Daniel
