123adama, not sure if I fully understand your issue but I'll try and give some suggestions:
When wishing to view/track and aircraft and you select it on your map, then try not move the mouse after that as if you do and it moves over another aircraft or aircraft label then it will automatically select that aircraft details.
If you select the aircraft on the MyFlights list and the list is jumping around, try clicking on one of the column header names that will sort the list in order of that column and reduces jumping.
If this does not help, please explain in full details what your doing and what is happening. The more detail the better.
