app working weidly

[Mustafa Kurayami]

hi all,
First of all, sorry for my bad english !
Well, I'm developping an app with a sliding Menu with some other content which slides too. It works fine on the emulator but when I deploy it, i have some problems :
- On a samsung star, the menu works but the other content slides veeery slowly
- On nokias 6500 and 6600 the first item of the menu shows itself and then nothing happens

Here is the code, Thanks for helping !
