Make grid ro text cells selectable

Suite 7.0/6.0/5.0 and Optimus Suite 5.0

The fix to make ro text cells selectable used to work before I upgraded to 4.2.1 suite

 myGridBox.entBox.onselectstart = function(){ return true; };

But not anymore. Anyone can give a working fix for this?

Using css like this doesn’t work either:
#myGridBox
{
-webkit-user-select: text; /* Chrome all / Safari all /
-moz-user-select: text; / Firefox all /
-ms-user-select: text; / IE 10+ */

/* No support for these yet, use at own risk */
-o-user-select: text;
user-select: text;
}

OK, found solution myself
Changing css to this works:
#myGridBox td
{
-webkit-user-select: text; /* Chrome all / Safari all /
-moz-user-select: text; / Firefox all /
-ms-user-select: text; / IE 10+ */

/* No support for these yet, use at own risk */
-o-user-select: text;
user-select: text;
}
