I have a WIAMinidriver dll and an ErrorHandler dll. both are installed successfully.

WIAMinidriver dll sends WIA_TRANSFER_MSG_DEVICE_STATUS message on a particular scenario.

ReportStatus() method of ErrrorHandler dll captures the message and displays an error message pop up.

ErrorHandler dll is called with some application like "Windows Fax & Scan" and "Devices & Printers" but not with "MS Paint" or third party Application like "Twaker".

Why the ErrorHandler is not called from all the Application?
