[Eeglablist] slowly scrolling plot

[Makoto Miyakoshi]

Dear Peter,

There was a problem with real-time refreshing speed, especially to obtain
the cursor position to read amplitude, in Matlab 2014b. Ramon has made a
partial fix so that when the cursor is outside the plotting window it does
not read the amplitude. I wonder in your case if the slowness is related to
it...
