i am developping a serial interface to use with a HID device. It uses its own threads for reading and writing.
Everything works fine, as long as i do not drag and move the application window or other open windows.
The HID device is sending the packets (i did check that), but some are lost by ReadFile(). I don't know where to search for the error, because ReadFile() does not fail.
I am using Visual Studio Express and i program with the WIN32 API.
I hope some of You got a hint for me.
