Ton,
I didn't have that problem, but if an error occurs before the workbook
is closed, the Excel object will still be active and locking the
output file. The Excel process then needs to be killed in Task
Manager. However, the locked file would prevent it being opened in
Excel as well.
Check in the Task Manager process list (ie. under the Processes tab)
that no instances of Excel are running before running the AFL code. If
AB still locks up, check the Task Manager process list again and see
any Excel processes are still running. If so, try killing them.
Otherwise I can only suggest using DebugView and trace statements to
find out exactly how far it gets, although if you say the XLS file is
being generated and that you can open it in Excel, then it would seem
that it is getting right through it.
