Hola Marcelo,

>This combo has to be refreshed when the user selects values in other controls, I try requerying it form that controls, but it never get the actual parameters, jusk keep the same as if it weren't requeried.

Have u tryied using the gotFocus() method of the combo instead
of when() ?

>Is there something to avoid the message with a thermometer showing the query progress ?

I think you have a SET TALK ON somewhere. Remember the scope
of it is the datassesion, so if your form has a private one
it should be in some of its methods, or in one of the base
class for it (load() or init() are good candidates).

HTH,
