Stopping the jump anim locks me in place?

ok, maybe i'm going about this the wrong way, but i'm wondering why i'm getting stuck. i'm using the below script to stop all animations but the one i want to play. for some reason, if i hit the jump button (pageup) the avatar doesn't even jump, and it locks me in place. i can still turn around, i just can't move from that spot. but if i sit on something and then unsit, i'm able to move around again. all other movement keys don't do this, even pageup/pagedown while flying. is there some thing in the viewer that the default jump anim needs to run for?

key id;
key animid;
string anim;

animate()
{
    anim = llGetInventoryName(INVENTORY_ANIMATION,0);
    animid = llGetInventoryKey(anim);
    list anims = llGetAnimationList(id);
    integer i;
    integer len = llGetListLength(anims);
    for(i;i < len ;++i)
    {
        string listanim = llList2String(anims,i);
        if(listanim != animid)
        {
            llStopAnimation(listanim);
            llOwnerSay(listanim);
        }
    }
    llStartAnimation(anim);
}

default
{
    on_rez(integer num)
    {
        if(llGetAttached())
        {
            id = llGetOwner();
            llRequestPermissions(id, PERMISSION_TRIGGER_ANIMATION);
        }
        else
        {
            llSetTimerEvent(0);
        }
    }
    
    run_time_permissions(integer perm)
    {
        animate();
        llSetTimerEvent(.1);
    }
    
    timer()
    {
        animate();
    }
}

aah ok, thanks
