Novice: Requires knowledge of the user interface on single-user computers.



SYMPTOMS
If you change toggle button controls in an option group on a form to option buttons (or, in some cases, to check boxes), you may receive the following error message, and then Microsoft Access quits.

In Microsoft Windows 95
This program has performed an illegal operation and will be shut down.

Pressing the Details button displays the following:

MSACCESS caused and invalid page fault in module MSACCESS.EXE

In Microsoft Windows NT
An application error has occurred and an application error log is being generated.

MSACCESS.EXE

Exception: access violation 0xc0000005, Address: 0x30036e02"



RESOLUTION
Delete the option group and recreate it with a different type of control within the option group. If any Visual Basic for Applications code is attached to the option group, you must recreate it also.



STATUS
Microsoft has confirmed this to be a problem in Microsoft Access 97. This problem no longer occurs in Microsoft Access 2000



Steps to Reproduce Problem

 * 1) Open the sample database Northwind.mdb, and create a new form not based on any table or query in Design view. Name the form frmTest.
 * 2) Add an option group to the detail section of the form using the Option Group Wizard.
 * 3) On the first screen of the wizard, enter aa, bb, and cc in the Label Names column, and then click Next.
 * 4) On the second screen of the wizard, click "No, I don't want a default," and then click Next.
 * 5) Accept the defaults and click Next on the third screen of the wizard.
 * 6) Click Toggle buttons for the type of controls you want within the option group, and then click Finish.
 * 7) Save the form.
 * 8) Change the toggle buttons to option buttons by using the right mouse button to click the toggle button, pointing to Change To, and then clicking Option Button. Repeat for each of the three toggle buttons.
 * 9) Save the form, and then close it. Note that you receive the error message when the form closes.
