Thank you for the reply.
All the three tests have been done already. Problem persists.
I use PMDG 737 and 738. Anti-virus off when using FS.
- activation FS in safe mode once, then normally.
- reinstallation of graphic driver: Geforce 7000 series, the latest driver.
Then all was OK, Acars Device worked fine. An then, during a flight it stopped showing the menu (but first the menu was on but the keys were not working - could not "go back" for example. Then the menu wouldn't show.
The next day morning - works fine. In the evening - no menu. So I reinstalled the aircraft, and reinstalled the FSFK. Removed the device using device installer, saved the configuration, and installed the hot spot and the device.
Then for two days, flying a few flights online - no menu.
After reading your reply I started the FS to test again on different acft - and all is fine again, the menu is suddenly back
. One more thing - I also use AS 6.5 set do download Vatsim weather - but now I've changed the weather to VATSIM in FSFK, maybe that's the reason.
Strange as it is...
