In a form I have precisely one place where I table.DisableControls. This is just above (one line) a try..finally block with a table.EnableControls in the finally part.

I've just had to add a table.enablecontrols into another part of code to get things working.

What else can disablecontrols?

Is this dbisam?

If so I notice that TDBISAMDataset.RecordFilter does not implement a try
finally after settempstate to restorestate which might increment the
disablecount and not decrement it if an exception occurs.

Thanks for the response.

Nope its ElevateDB, and also no exception has occurred.

This is also an issue with EDB, so I've fixed it in both.

Thanks, but would it also cause the problem when there's no exception?

Roy,

No, only when there's an exception in the OnFilterRecord event handler.

As far as I know, nothing but a DisableControls. Maybe you could try
commenting out the initial DisableControls and try adding some
TDataset.ControlsDisabled tests in your code and maybe you can figure
out what method is causing the stray EnableControls.
