Well,
I tried flying again after leaving ixeg and x-plane alone, waiting for the update.
Tried a few "circuits", just take off, engage auto-pilot and turn back, intercept ils, and land.
In many cases the auto-pilot disengages, and I have trouble getting it back in order.
While intercepting the ils, I press APP, and most of the time, the auto-pilot does not go in APP mode, neglects approach paths, although I manged one or two successful auto-lands.
I did the same with the default 737, and with the PMDG 737 in FSX, and all works as expected, no problems for me doing circuits and ils/gs interceptions.
It has been some time ago since I tried flying the ixeg 737 (previous version), but I cant remember having these problems, but it may be my ignorance. Been flying it with FMC and all, worked fine, then.
(oh, and the plane turns like a bumper car on the ground, totally unrealistic)
??
(can the speedbrake have a click sound??)
