FileDialog is showing a blank white window for me. Only tested on windows 7 so far, but if I run dmledit, the filedialog on there works fine. It's weird because I am using almost exactly the same code.

Here is what it looks like

handleAction code:

>                case ProgramActions.FolderOpen:
>                	UIString caption;
>                    caption = "OPEN_DIR"c;
>                    FileDialog dlg = createFileDialog(caption, true);
>                    dlg.dialogResult = delegate(Dialog dlg, const Action result) {
>                        if (result.id == ACTION_OPEN.id) {
>                            string filename = result.stringParam;
>                            //TODO
>                        }
>                    };
>                    dlg.show();
>                return true;
> 
>                case ProgramActions.FileOpen:
>                	UIString caption;
>                    caption = "FILE_OPEN"c;
>                    FileDialog dlg = createFileDialog(caption, false);
>                    dlg.addFilter(FileFilterEntry(UIString("D_FILES"c), "*.d"));
>                    dlg.addFilter(FileFilterEntry(UIString("ALL_FILES"c), "*.*"));
>                    dlg.dialogResult = delegate(Dialog dlg, const Action result) {
>                        if (result.id == ACTION_OPEN.id) {
>                            string filename = result.stringParam;
>                            //TODO
>                        }
>                    };
>                    dlg.show();
>                return true;

Here is my createFileDialog

>    FileDialog createFileDialog(UIString caption, bool folder, bool fileMustExist = true) {
>        uint flags = DialogFlag.Modal | DialogFlag.Resizable;
>        if (fileMustExist)
>            flags |= FileDialogFlag.FileMustExist;
>        if (folder)
>            flags |= FileDialogFlag.SelectDirectory;
>        FileDialog dlg = new FileDialog(caption, window, null, flags);
>        //dlg.filetypeIcons[""] = "";
>        return dlg;
>    }

also have this in handleActionStateRequest:

>                if (!_currentBackgroundOperation)
>                    a.state = ACTION_STATE_ENABLED;
>                else
>                    a.state = ACTION_STATE_DISABLE;

Try fetch recent dlangui version (dub upgrade --force-remove).
I fixed this issue last week. (There was a problem with sharing of OpenGL context between windows).
Difference in dmledit is probably due to different dlangui configuration selected - it uses `minimal` configuration - w/o OpenGL acceleration.
