Grrr ...
Ok, now I want to know whether - and how much those commands are being processed by XXHighEnd ...
Be sure to have a TemporaryData folder under your current XX folder (it isn't created automatically in this version per a bug).
Set the Loggin On.
Start Playback as always (Unattended), and use Alt-U one time.
Wait one minute or so.
Don't touch anything further, but get the XX and X3 log files (X3PB is not necessary), and post them.
Notice that in order to do this conveniently you should have an Explorer instance running, so you can grab the files.
After you caught the files, you can stop playback.
If you want of course.
Sorry AGAIN for the troubles ...
