ACCESS 2002 enters some kind of endless loop and crashes

D

Hi,

Database: developed in Access 2000 on Windows XP,

On a laptop running Access 2002 and Windows 7, I have the switchboard
set to open on startup.

When the switchboard opens Access enters a loop that presents the
informational message:

NCMR Tracking can't move the focus to the control Picture.
*The crontrol may be a type that can't receive the focus, such as a
label.
*The control's Visible property may be set to No.
*The control's Enables property may be sent to No.

There is an OK button.

When I click the OK button, it pops up several more times from (1 to 8
times), and then windows presents a message:

Microsoft Access for Windows has stopped working

A problem caused the program to stop working correctly. Windows will
close the program and notify you if a solution is available.

The form shows a "Close program" command button.

The switchboard--created with the Switchboard manager--has an on
current event procedure and an On open event procedure, both listed
below.

I do not see this message on a desktop running Access 2000 on Windows
XP. Nor do I see that message on a laptop running Access 2000 on
Windows7.

On a laptop running Access 2002 on Windows 7, I added breakpoints to
the event procedures, but I can see no code is highlighted, and I have
been unable to determine how to debug this situation or to find what
is causing the messages.

Does anyone have any suggestions?

Thanks,

Dan

Well, I think I've found a way to fix it.

I created a new database in Access 2002 on the laptop and imported all
the tables, forms, queries and modules.

The new database opened without the messages. Then, the original
database opened without the messages.

It seems to be working.
