Check the backcolor and disabledbackcolor of the boxes that are working properly for the correct settings. VFP6 seemed to have different defaults than VFP3. I had a few wonky things like this after conversion.

Best best is to make a base class for all of your textboxes and get the behaviour settled there.

>Hi All,
> I think I've seen a problem similar to this addressed here before but I can't remember when. I'm converting an application from VFp 3.0b to VFP 6.0 (SP3) and am having trouble with the background colors of textboxes (and edit boxes). Here is the scenario:
>
>I have a form which has a container which in turn contains a pageframe. When I click on any text box on page 1, everything works as expected. However, when I click on page 3 (which contains a grid), and then click back to page 1, all of the text boxes have the background greyed. I can still access all the fields and when I place the mouse in a text box the background changes to white (just as it should always be). If I click on another field, the first field may or may not revert back to a grey background and the field I just clicked in has its background change to white.
