For some reason (I think that it happens when the data which is inserted the columns is bigger than the lenght of the columsn), clicking the line that was added sometime causes a blink in the text.
/window -aln -t2,3,6,8,10 @saragani
//aline @saragani aaaaaaaaaa $chr(9) bbbbbbbbbb $chr(9) cccccccccc $chr(9) dddddddddd $chr(9) eeeeeeeeee $chr(9) ffffffffff
Now clicking on the line that just added (Try it more than once, cause it doesn't always happens) will cause the text to blink for a moment on a different position.
On the example I gave, the problem isn't that bad, but in some causes it is realy ugly. I tried printscreening it, but it is impossible to do it (Possible maybe only with screen video capturing).
I hope that someone understands what I wanted to say....
