What you are describing sounds like it should Just Work, so in the absence of seeing more of your code, I'd speculate that the callback functions are not using the global songCounter var at all, but instead you have (presumably accidentally) shadowed the global with a local redeclaration. If you can post some of your code so we can take a look, that might help clear things up. Ideally, if you can post a small but complete and compileable example here, that exhibits the fault, then we can can try it... _______________________________________________ fltk mailing list fltk@easysw.com http://lists.easysw.com/mailman/listinfo/fltk
