[Laszlo-dev] What was the reason for setting document.onselectstart in LzInputTextSprite?

[Max Carlson]

Also see LPP-4170 - Edittext does not allow mouse to highlight entered 
text in dhtml.

Henry, here's how I found these:
$ svn blame LzInputTextSprite.js | grep onselectstart
   6826        max     document.onselectstart = null;
  13912        pbr         document.onselectstart = 
LzTextSprite.prototype.__cancelhandler;
   7295        max document.onselectstart = 
LzTextSprite.prototype.__cancelhandler;

Of course that only shows the most recent change for those lines - I 
searched my checkin history and it looks like the original change was 
from r1035(!):
Turn off text selection in OE[sic] DHTML - fixes dragging in LzPix
