[Lazarus] Application slow shutting down

[Susie Nicol]

Hi

I have an application with a main form, and several others whuich are only
ever used in modal form.

The application is slow to terminate, and I cannot see why.  The shutdown
procedure, simplified a little looks like this: (datamodified a global
Boolean; savedata another procedure in the same unit; the SQLcomponents are
in a a data module)

procedure FinishUp;

begin
  if datamodified then
    savedata;

 sqltransaction1.commit;
 sqlconnection.close(True);

Application.Terminate  {line A}

end;

The debugger shows me that everything is fine until line A, when the
program hangs: often for 15 seconds, sometimes for ever.

XFCE on Linux complains that the window containing the main form cannot be
closed because 'the application may be busy'.

I have tried to replace line A with 'halt' or 'close' without any
difference. The connection to the database is indeed closed.

I am using Lazarus 1.4.2, 64-bit, Linux XFCE desktop, GTK+2 widget set.

Any suggestions about where to look next will be very welcome.
