have some strange bugs - help appreciated

[101 bassdrive]

hi. Ive always had some minor bugs going on, but most of them Id already encountered in vanilla so I didnt bother.
but lately with 0.5 some new1 have showed up which sometimes are a bit of a pain:

1. ingame keyboard setting keeps switching from european qwertz to qwerty.
I have absolutly no clue why since the bf2 options dont have a setting for this.
please dont start a rant on me bout using VOIP, i do so in squad teamtext is still vital.

2. dodgy behaviour of airvehicles and motobikes.
this happens in shiny new spawned helos and jets. the horizon will just instantly flip to the side from one frame to another and stutter really bad, making it really hard to controll since it happens so incredibly fast.
it mostly happens randomly. though the A10 on basrah always seems to have this problem. while on greasy mullet I can fly it smoothly.
it also happens rarely in the attackhelos and blackhawk. the LB works fine.
also the jihad bikes on all maps stutter around I can barely get around corners with em.

hope you guys can help me out how to fix these things, id really appreciate it.

the keyboard change is a windows thing. Delete all others keyboard settings that might have nested there, and just use the one that is for you specific keyboard setup. ( probably US-International 101 )

Also try to find out if there are any shortkeys for changing the keyboard layout.. That might be a issue.. But i think the first option would stop it..

The motorbike is bugged or something. Its really dodgy, you have to get the hang of it.
