[jitter] Bug report: jit.cellblock jumps to lowest visible row when navigating with arrows

Hi Mattijs,

I can confirm your observation regarding the arrow key issues. I'll send 
it on to the appropriate person.

You may have already figured this out, but if you would like to have 
cellblock scroll to the selected location, i recommend using a 'sync 
click' message as well, like this:

#P window setfont "Sans Serif" 9.;
#P window linecount 1;
#P message 76 160 149 196617 select \$1 \$2 \, sync click \$2 \$1;
#P newex 76 121 27 196617 pak;
#P number 120 95 35 9 0 0 0 3 0 0 0 221 221 221 222 222 222 0 0 0;
#P number 76 95 35 9 0 0 0 3 0 0 0 221 221 221 222 222 222 0 0 0;
#P user jit.cellblock 76 222 358 457 3 9 20 20 45 17 0 1 1 0 1 1 1 1 1 0 
0 0 255 255 255 0 0 0 0 0 0 191 191 191 0 0 0 215 215 240 1 1 1 0 4 0 0 0;
#P connect 4 0 0 0;
#P connect 1 0 3 0;
#P connect 2 0 3 1;
#P connect 3 0 4 0;
#P window clipboard copycount 5;

all the best,
-Ben
