HI Dave, I think I wasn't very clear in my last post. What I am really saying is that after deleting the C-130 DEMO file from my airplane folder in my computer, I have been experiencing odd behaviours with my other planes in general. For example, I flew a B737-900 from Pearson Int to Detroit and as soon as I climbed 1500 Feet, my plane kept going pass 250 knots and kept going and going, even thought i had set the speed hold for like 285.
I also noticed something else, the altimeter Flying tip shows up quite often, when before installing this demo, it rarely came on!
I am not a very knowledege person when it comes to controls and gauges in FSX but I really would like some help fixing this.... any ideas? :-/

update: I found a file called:TCAS2v7 and it was I listed the files by Date Modified, and I found this inside:
[Filtering]
Range=100
Altitude=100
Speed=30

[Smoothing]
Enabled=1
MaxCoast=20
Alpha=0.4

[Logging]
Enabled=0

which is weird because the speed of my current airplane is automatically set for 30, even though I am not moving at all! :-? :'(
