Hi everybody, I have a multi-thread FLTK 1.3 application on Win XP. The problem is that when the application tries to print (using Fl_Printer) all threads get blocked while the Windows printer selection dialog is open. In that case the method Fl_Printer::start_job() was called from a callback (from main thread). So to prevent the application from blocking I decided to create a working thread that calls Fl_Printer::start_job() ⦠Fl_Printer::end_job(). With this change, the application doesnât block itself while the dialog is open but blocks forever after printing. I suspect that Iâm doing something wrong since I know that no window should be open or close from threads other than the main one, but I don´t know what would be the right way to implement this. Thank you very much. David
