The problem appears to be caused by display of UTF-8, such as boxes. Here is a display from a fresh session; on each line the cursor was at the end of the line when ENTER was pressed, so that select should be the same as the length of the term window:

The 3 numbers are (start of selection),(end of selection),(length of term window text)

   (0 ". fs), #ft [ 'ft fs' =.  {:"1 wd 'sm get term;'
54 54 54
   (0 ". fs), #ft [ 'ft fs' =.  {:"1 wd 'sm get term;'
118 118 118
   (0 ". fs), #ft [ 'ft fs' =.  {:"1 wd 'sm get term;'
185 185 185
   <1
┌─┐
│1│
└─┘
   (0 ". fs), #ft [ 'ft fs' =.  {:"1 wd 'sm get term;'
270 270 286

select has fallen 16 characters behind. 16 is exactly the number of extra bytes added in converting the 8 boxing characters to UTF-8.

there appears to be some magic with

WinSelect_jqtide_
WinText_jqtide_

but accessing these seem to get stale quickly.  ie. doesn't grow despite more 
getting added to console

this line does update a new "winselect" but it seems out of sync

(400 (i.@[ + -~) 0 {.@". fs) {ft [ 'ft fs' =.  {:"1 wd 'sm get term;'
should print the last 400 characters, but

   (0 ". fs), #ft [ 'ft fs' =.  {:"1 wd 'sm get term;'
94123 94123 160296

   (0 ". fs), #ft [ 'ft fs' =.  {:"1 wd 'sm get term;'
94238 94238 160370

   (0 ". fs), #ft [ 'ft fs' =.  {:"1 wd 'sm get term;'
94312 94312 160444
   (0 ". fs), #ft [ 'ft fs' =.  {:"1 wd 'sm get term;'
94386 94386 160518


the last select value is well below the character count.  These are 4 
successive calls.  Select does not go up by a consistent amount and neither 
does Textcount, though in the last 2 calls there is a consistent 76 increase in 
select and 72 increase in Text

If I were to guess what is happening, for the large discrepancies, is any 
output from 1!:2 does not update fs.

I can point out that finddissectline_dissect_ as a user key breaks fairly 
quickly after starting jqt.  Though it does work on startup.
