I have attached a patch with a few debugln in it. I don't know if they 
will show anything useful, since I have no idea what is going on.
If you apply it, you need to start lazarus with a logfile, to capture 
the output. (There is a command line switch, but I have to find it 
myself / I usually compile as none "window app", which means my Lazarus 
runs with a console-window showing all the output)

Also if you do this, test it with only one Synedit open. (You can 
compile a standalone app, with one SynEdit, and set the font from inside 
the app)

Memos are native controls, so they are drawn differently.

If you use the same font, (and in normal, bold, italic) for Labels 
and/or StaticText, does it look correct there?
Note, the spacing will be ok there, because neither of them forces the 
mono-spacing. But does it actually look like the expected Courier New, 
and is it truly monospaced?
