I'm having a strange issue with using FileOpenDialog to select a file. Everything works fine the first time you select a file. But if you change your mind (while the program is still running) and want to select a different file, nothing changes. The program is "stuck" with the first selection you made, and nothing you do will change that selection in the input box. I pulled the function below out of my program, and I had to modify it a bit to make it run on its own. But it's basically the same as the original. To see the problem in action, click on either of the two buttons that say, "Choose other file...". Select any file from the list. Click on the "Open" button. So far, so good. Now, repeat the process again. See? The original file you selected is still listed in the input box. I'm stumped by this one.
