Good call on the $HWNDPARENT thing. Apparently I was foiled by a word wrap
. It works now, many thanks.
In the NSIS User Manual (that I got with 2.0 Final), under 4.5.2 Page Options, it seems to say that the only two things you can use specifically in a directory selection PageEx block are DirVar and DirText. Apparently that's not the case.
Also, when you click them from there, it takes you to 4.8.1 General Attributes, which seem to be mostly "global" settings (ChangeUI and CRCCheck) and some which are specifically noted as being used only in a PageEx block (DirVar). Maybe a note should be added to DirVerify as well to say that it can only be used inside of PageEx.
I also happened to find something called SpaceTexts, which kind of looked like it might have been the right way to do this. It seems odd to me, though, that you can only disable both texts at once, and not specify one or the other.
Anyways, I think NSIS is great, and the service on the forum is amazing. Can't thank you enough for the effort you're putting in.
