file is in same folder as sketch -- it is also included ?
Only if you use the right syntax. This syntax:
#include <TouchScreenMenu.h>
Will only cause the include path to be searched.
This syntax:
#include "TouchScreenMenu.h"
causes the local folder to be searched, then if the file is not found there the include path.
Your problem is different from elanozturk's because they did use the correct syntax for a local file.
