I use a different thread. I never got polling to work right in the Pascal stuff in my program. I could send you PAscal code that worked for me in Free Pascal, and probably will work in Delphi, but I assume you are using C.
One quick test is to do away with the GUI, and just run your program directly in a console window and see if it works there. Just double click ti and you should get a window. Type "uci"<Enter> and see if it gives the engine name and parameters. A simple "go depth 10" shoudl do a 10 ply search. If the program ignores the input this way it might be a clue.
