As it turns out this problem was due to non functioning livery scripts that I added sometime ago in the aircraft cfg. folder. I deleted them out and all is back to normal once more with that problem. I am still having glideslope issue though. Cleaned out registry, reinstalled 1.3, using C172 as default before loading the 707 and still have the same issue. Glidesslope is staying at the bottom of the indicator not moving. Just on fligths more than 30 min. Oh well.
