[texworks] SCRIPTS: TW.getItem() returning everything lower case?

[Paul A Norman]

Oh well, its still there some times -

var optionsList = new Array("Abcd","abcd","ABCD","ABCD","Efgh", "EFGH");

didn't completely solve it.

I'll focus on Qt forums - unless someone comes up with another idea here.
