Hi, X Error of failed request: BadDrawable (invalid Pixmap or Window parameter) I'm not sure what this means, as all I've been able to read is that perhaps I haven't freed a display, but to the best of my knowledge I have. If you want to look at the code causing this, look at https://github.com/2mb-solutions/bash-it.git (note: Has submodules). -Michael. |

I can't begin to guess what's causing this, but my understanding is that the 5.1 branch has many bug fixes and is actually considered more stable at this point despite the developers being free to make breaking changes (which doesn't seem to happen often). You can try to eliminate bugs in Allegro by building with Allegro 5.1... I've only glanced at your code, but there are several alarm bells. You're ignoring return values[1] (which in C is your only indication of failure, which whether you think does or not, DO happen). Probably worse is the global variables. I gave up trying to spot the problem quickly because it's honestly not worth trying to weed through such poor code. Only a long session with a debugger has any hope of figuring it out, but even if you get past it now you'll just end up right back here again and again. You need to learn best practices to start and refactor the code... -- acc.js | al4anim - Allegro 4 Animation library | Allegro 5 VS/NuGet Guide | Allegro.cc Mockup | Allegro.cc <code> Tag | Allegro 4 Timer Example (w/ Semaphores) | Allegro 5 "Winpkg" (MSVC readme) | Bambot | Blog | C++ STL Container Flowchart | Castopulence Software | Check Return Values | Derail? | Is This A Discussion?

Sounds like an interesting project! 1int main()
2{
3al_init();
4al_install_audio();
5al_install_keyboard();
6al_init_acodec_addon();
7ALLEGRO_DISPLAY* disp = al_create_display(640,480);
8// Generate the main menu.
9string options[] = {"play","exit"};
10dynamic_menu* mainMenu = create_menu(options, 2, NULL, 0);
11mainMenu->set_display(disp);
12int r = mainMenu->run_extended("", "", 1, true);
13if (r == 1)
14{
15
16}
17}
