Clear Status button in Order Entry (Global Equities ...) example triggers Sub ClearOrderStatus.
My version of this Sub code does not call addDDE, neither it introduces RediLink calls (found in addDDE), but yours may be different version, and likely is enhanced/modified.
Please examine your ClearOrderStatus code, do you see addDDE call or direct RediLink calls? Then comment this code out. Otherwise, share your Sub ClearOrderStatus code.
