[BUG] Dolphin 4 class delete bug

A small bug in Dolphin 4 Professional, patch level 1, Windows 98.

1) In the Class Browser.
2) Create a new class using the menu (Class/New).
3) Switch to the 'Class Comment' tab, enter a comment. Do not accept
   the comment (via Ctrl+S), just leave it as entered.
4) Switch to 'Class definition' tab.
5) Right click on class name in left hand tree pane, and choose
   Delete. Confirm to delete the class.
6) Message Box pops up asking "There are unsaved comment changes. Do
   you wish to retain them?".
7) Click "Yes" in the message box. It then appears to get stuck in a
   loop asking the same question and neither yes or no stops it. You
   can't  use the class browser as the message box has the focus.
