I have been researching a problem pertaining to a Visual FoxPro5.0 application. When the user attempts to change the selection in a combo list box they receive the following error message:
"Error number 13 in maintenance.pageframe1.page1.cbroker.gotfocus line 0". Then when the user clicks anywhere on the application they receive another error message, only this time it references 'mousedown in line 0'. Then the application returns to normal.

I have done the following research to narrow down the problem:
The particular information in the 'view' used for display in the combo list box is irrelevant. It appears to be the position of that record, in particular record #253. All other selections in the combo list box are valid and do not give errors.

The following information pertains to the property settings for the combo list box:
boundto = .T. ; columncount = 2 ; columnwidths = 70,100 ; controlsource = vendor.nbrokernum ; firstelement = 1 , number of element = 0 ; rowsource = broker_view.nbrokernum, cbroker ; rowsourcetype = 6 ; style = 2 ;
method requery:

select broker_view

=requery()

Does anyone have an idea why only one record in a view gives the above errors?

Thank you for your time ........ John
