In Buffer Mode 5, the coding for Tableupdate():

IF TABLEUPDATE(.T.) == .F.
	WAIT WINDOW "Fail in Update Old Record" NOWAIT TIMEOUT 10 
ELSE
	WAIT WINDOW "Success in Update Customer!!" NOWAIT TIMEOUT 10 ENDIF

But Not matter how many times user click Update Button, it still fail!!

What can user do!?

On the Contrary, if user use another function and reopen the same table again, it can update it at that area!!
whereas if return back to old work area, the data can't update!!

I want to know why fail to update if both workarea are set Buffer mode 5!
