Apple Logic Pro /LogicExpress Discussion

(just suffered a kernel panic crash before sending these questions, so I'm typing this 
lengthy inquiry for the second time - please excuse me for my gruffness):

I have two issues:

1) This has been plaguing me for a long time (it even occurred in LP 7). Working last 
night in the piano scroll editor with MIDI data, the situation arose where moving note 
data (X or Y axis) caused the window to leap to the head of the region upon release of 
the mouse button, necessitating scrolling back to the data work locus. I don't know why 
this happens but it has happened before and it seems random. I have been unable to 
notice anything about my work state when it starts, but once it starts, it seems to be 
consistent behavior for that session. Sometimes just clicking in the editor widow causes a 
jump to the head of the track. Am I missing something? Can anyone help on this? It sure 
is an annoyance.

2) (and more importantly)

This one only appears in LP8:

Sometimes I'll be working with MIDI data, editing the velocities in the graphical controller 
and velocity data area, and, after performing some other work (on a different 
track/region, for instance), I'll re-select the track in which I was editing the velocities, but 
the velocity data goes missing from the editor - just a blank field below the piano scroll 
presents itself. Usually it's correctable in a few steps (e.g. turning the graphical editor off 
and re-opening it), but l sometimes I  can't get the "dots" to appear even after taking 
those steps or even re-loading the app.

And last night came this new diabolical variation:  pasted data from another region failed 
to display its controller data, while pre-existing data did show in the editor.

Here are links to two screenshot  jpgs I made showing the variations I've just relayed:

Love to hear from someone (I'm going to preview this - please don't crash!)
