Try to find out how standard Win32 (and thus NOT MFC) is doing the
on folder change thing in the file open/save dialog handling
(e.g. by searching Microsoft's SDK descriptions).
Then you can deduce the way Wine is supposed to handle this.
The relevant code is in dlls/commdlg/filedlg*.c
If there is anything else you need to know, then just ask here.
This folder change checking is not done via Win32 file change notifications
by chance, or is it ??
In this case it's not too suprising that it doesn't work:
the Wine Win32 functions print a FIXME, and the whole thing is rather
difficult to implement: most likely it'd require full-scale support
in the operating system file system layer.
Good luck !
