Welcome to the TeXworks community, then :).

Hmm... As far as I know, Qt (the library Tw is built on top of)
unfortunately has some problems with accessibility support (though so
far this has mainly come up in connection with screen readers, I think).
So the first question is where the problem is - in Qt, or in Tw. To
determine that, could you download the program
http://web.student.tuwien.ac.at/~e0325258/projects/c/texworks/hidden-selection.exe
and run it? It's a very bare text editor widget produced by just a few
lines of code (btw, the name comes from the fact that I wrote this for
another bug report some time ago). If the magnifier works with it, there
is some problem in Tw. If not, the problem is most likely in Qt.

One alternative I can suggest (though I don't know if it would help) is
to turn up the font size in Edit > Preferences... > Editor (you'll need
to restart Tw for this to take effect).

PS @Johannes: "Follow Focus" doesn't help here. If activated, the pdf
previewer scrolls automatically according to the current cursor position
in the editor - but it has nothing to do with external tools such as the
Windows screen magnifier.
