Hello,
I have this situation and it just happens this week,as I can recall.
It only occurs with the PMDG B737 series.
I have tried all the other a.c. from PMDG and the a.c. from FSX but it is only B737.
When I load the aircraft it loads with the parking brakes set.
Pressing the dot (.) does actually releases the parking brakes, but the text remain there.
Applying ctrl+. does engages the parking brakes, so it functions.
How can I make the text disappear when the parking brakes are released??
It is just annoying for I have to check whether the are released or not.
Carlos
