SYMPTOMS
There is a problem in the Video Poker Game sample included with Microsoft Fortran PowerStation 4.0. If you change a value of one of the scoring hands payoff values in the Poker Paytable dialog box and press the ENTER key while the changed payoff value edit box has the focus, the OK button callback routine isn't called. Consequently, the changed payoff values are not saved. This problem also occurs if you press the OK button's shortcut keys (Alt+O).

The OK button's callback routine is called and the payoff values saved only when the user clicks the OK button with the mouse or presses the TAB key to move to the OK button and then presses the ENTER key.



CAUSE
The IDD_POKERPAY dialog box has two different OK buttons, one directly on top of the other, and both are selected as the default button. The dialog box manager is picking the IDOK2 (not visible) OK button when you exit the dialog, but the callback function is expecting the other button IDCHECKOK (visible) to be the default.



RESOLUTION
Remove the IDOK2 button from the IDD_POKERPAY dialog box. In Developer Studio, with the Video Poker Game project open in the active workspace select the Poker.rc file from the file viewer and open the IDD_POKERPAY dialog. Once the dialog is open, highlight and drag the visible OK button to one side (IDCHECKOK). This should reveal a second OK button hiding directly underneath the first one (IDOK2). This is the button that must be removed from the dialog. Select it, and delete it. After deleting the IDOK2 button, move the correct button (IDCHECKOK) back to its original location, and rebuild the Video Poker Game project.



STATUS
Microsoft has confirmed this to be a bug in the Microsoft products listed at the beginning of this article. We are researching this problem and will post new information here in the Microsoft Knowledge Base as it becomes available.



Steps to Reproduce Problem

 * 1) Copy the "POKER: Video Poker Game" sample files from FPS 4.0 Books Online in the Samples/General section to your computer's hard disk.
 * 2) Run the Poker.exe program and open the Poker Paytable dialog box by selecting the Edit Paytable option from the Game menu.
 * 3) Change the Royal Flush edit box value to 200, and press the ENTER key, or press the OK button's shortcut keys (Alt+O).
 * 4) From the Game menu, select the Edit Paytable option again. Note the value entered in the Royal Flush edit box in Step 3 was not saved.
