Similar to #120, try these steps:

1. Create a new DOS disk image or open an existing one.
2. Click Import… in the toolbar.
3. In the Import Wizard, note that the Remove and Edit… buttons are disabled because there are no items yet.
4. Click Choose… and select any file. The Remove and Edit… buttons are still disabled because no items are selected.
5. Select the file you added. The Remove and Edit… buttons enable.
6. Click Edit…, then click OK.
7. The list item has been deselected but the Remove and Edit… buttons are still enabled.
8. Clicking Remove causes the Remove and Edit… buttons to be disabled, but instead clicking Edit… causes AppleCommander to crash.
