MDI Refresh (Delphi 7)

Hey, geez there are a lot of places to post around here. Hope this is the right spot.
Hi I’ve got a MDI Parent form with a TLabel and TButton component on it. When I click the button, I change the caption property of the TLabel comp. However, the change does not reflect until the form is repainted (ie. drag it out of the screen area and back). Calling the form’s repaint / refresh methods do not have the same effect. any ideas?

my apologies, hadn’t read the sticky about Delphi / Pascal postings.
