hi there, I've installed the PMDG 737NGX a few hours ago and I'm absoluty fascinated by the level of detail, but I have a big problem. I'm not able to release the parking break! by pressing period key nothing happens :(. When I'm releasing the parking break in the VC, the red light distinguishes but I still have the notice of a set parking break in the lower left corner. The parking break works well with all over aircraft! Does anyone can help me? Cheers,Flo
