quick disconnect issues

I'm having some issues with the quick disconnects on my ball lock cornys. It's been about a week since I kegged my second and third kegged beers. I moved my kegerator this afternoon at the request of swmbo and when I went to reconnect my lines I had a hell of a time getting one of the gas lines back on the keg I had to really force that thing on there. Finally got it back on and then I had the same issue with the liquid out line on the other keg. I definitely have the posts on the right sides, I made sure to keep the notched posts with the in side of the keg. A couple minutes later after trying a bit of the green beer I noticed that the same liquid out line was leaking from within the disconnect. If I remove the disconnect it holds a seal. Finally, I've also noticed that if I don't have the co2 disconnects sitting just properly they will audibly leak gas. Any advice on my many disconnect issues? BTW I didn't have any of these issues on my first kegged beer, except for the co2 leak if not sitting properly.
Thanks for the advice.

Try some keg lube on the poppets. It works wonders for sealing and ease of assembly.

I agree that it helps. I had the same issue but it was a lot worse. I was taking off the liquid line and the poppet got stuck to the side and I got shot in the face with beer. It exploded all over my room and even my TV had it on the LCD.
