Requery problems

[ALui]

Hi, I'm working on a tabbed search form that has text boxes to search a query.
I have the textbox OnChange event to requery, but when it requeries its focus goes to the tab and I have to enter in 1 letter at time to continue searching. Is there some way I can prevent this, or at least redirect focus to the end of my string without selecting the characters I've already entered?

How bout the code on a different event.....

It works just fine on Lost Focus, but my client has asked me to try and get it to requery each letter to narrow down the patients in the search form.
