title: FLTK Modal Windows
body: <p>I have an FLTK program that has a base GUI and occasionally pops up a window for notifications (a custom function that is very similar to the win32 function "MessageBox"). The window is created when the program starts, and remains hidden for most of the run time. On linux, the show() function works perfectly, the window pops up and is modal and works fine. When compiled with mingw and run under windows, however, the program hangs when the modal window is shown. It seems like it gets focus but never appears. Can anyone explain this? Thanks.</p>
