How do you jump to 0, did you make sure it actually resulted in what
you want?

Here's the AppNote AVR109 way (that is proven to work):

void (*funcptr)( void ) = 0x0000;

okay here's another stab in the dark. when you make a function pointer and initialize it with an address (0x0000 in the case) is it the data i.e. the address stored in the .data section? this would mean that when i reprogramming from the bootloader i am overwriting this necessary initialization data and so the jump is not going to the right place and keeping me in the bootloader.
