okies... so I have tried writing a uint64 of my bobber GUID to 0x0127770 and pressing my "interact with target" key on the keyboard. that don't work.
and I have tried writing to 0x0127760 and pressing my "interact with mouseover" key on the keyboard. that don't work for me either.
I know the values are being written because I have a little app reading them to monitor when they are written so I can see the changes in the GUID as I cast my bobber each time.
I even tried getting the GUID of a vendor, writing it to the addresses and pressing my interact keys to see what happens. the address gets written but the vendor's portrait doesnt pop-up on my screen as it normally would if i clicked him myself.
