Was renaming the method and changing any code references to the method the only change you made between the grid working and not working? Are you sure the grid is being destroyed, and just not being built in the first place? For example, after the form is finished with its init, is the RecordSource set to what you expect and is the RecordSource populated? What happens if you reset the RecordSource?

ThisForm.MyGrid.RecordSource = myCursor

for example. You probably know that the classic cause of a grid being destroyed is requerying the RecordSource without first setting the RecordSource to "".
