I find mine sticks most of the time, it's the left side ( right as you try and open it) with mine. I can adjust it but it doesn't seem to last too long before I'm back to square one! Either get someone to hold the lever for you, or do what I do, hold the lever up with a roll of masking tape or similar, then, gently bounce the offending side until it 'pops up'. I consider it as my Corrado having character rather than a problem! :)
