Fix Cost Break timer crashes and memory leaks
Shipped in Margin Master 2026.904.35423 · September 5, 2026
Resolved multiple threading issues in the Cost Break dialog that caused crashes when editing pricing levels and left timers running after closing the window. Fixed boundary drift when updating pricing levels and ensured proper cleanup when the dialog is closed.
