Uploading a Mission blocking GLOBAL_POSITION_INT

Hi,

I am dynamicaly uploading a mission to the copter while in mid flight.

This procedure can take sometimes for a couple of seconds.

I have noticed while in the process of uploading a mission i am not receiving any GLOBAL_POSITION_INT msgs, however i recieve HEARTBEAT msgs - any ideas?

see below (in this example there are no position msgs for about 4 seconds):
