Pushback not working on PMDG 747v3

[Rhinozherous]

Hello'

I use GSX on FSX with the new pmdg 747. I am on the latest GSX version via live updater.
I am able to open the GSX menu and select the "prepare for pushback" entry. The pushback truck appears and I can select an operator. But after this, nothing happens. It dont asks me which direction or something... No new window pops up.

Thanks in advance for any help

Please indicate the airport and the gate where this happens. Possibly, a default airport, that we can verify this.

Because I didnt know anymore which Gates it was I tried it now on an default airport... and it worked. I will see how it works on my next flights. If I experience it again I will write the exact airport and gate and other circumstances here.

Thank you
