note syphilis Perhaps in the "non-Tk script" you can include an END{} block - something like: <code> END{$obj->Kill($exitcode) if $obj->GetExitCode() == STILL_ACTIVE}; </code> For that to work you'll need to be using version 0.10 of Win32::Process and you'll need to load the module as: <code> use Win32::Process (STILL_ACTIVE); </code> Even with earlier versions of Win32::Process there's probably a way of doing it - assuming that the END{} block is the way to go - which I've not properly tested. In fact you might even find it sufficient to simply:<code> END{$obj->Kill($exitcode)}; </code> which would work for earlier versions of Win32::Process, too.<br><br>Also check the syntax of the GetExitCode() call (if you find you need to use it). The docs have it written as <code> $ProcessObj->GetExitCode($exitcode); </code> but supplying an argument doesn't smell right to me.<br><br>Cheers,<br>Rob 553965 553965
