You are already braking! Break something to stop braking!
In earnest: Lutz' hint on switching to a textbox is right on topic.

Create it, call it Label_Dynamic and switch all your modifying labels over to that class and cut down on refreshes, esp. those called on whole containers - they don't discriminate and punish all controls...

vfp gives you C++ runtime speeds for dynamic controls changed via changes to .ControlSource, while you are recreating that functionality in vfp code. Going against vfp "flow" and probably even worse than going against DRY to recreate something already done better...
