+wxWindows 2 can be used to develop and deliver applications on Windows 3.1, Win32s,
Windows 95, Windows 98, and Windows NT. A Windows CE version is being looked into (see below).<P>
wxWindows 2 is designed to make use of WIN32 features and controls. However, unlike Microsoft,
we have not forgotten users of 16-bit Windows. Most features
work under Windows 3.1, including wxTreeCtrl and wxListCtrl using the generic implementation.

+However, don't expect very Windows-95-specific classes to work, such as wxTaskBarIcon. The wxRegConfig
class doesn't work either because the Windows 3.1 registry is very simplistic. Check out the 16-bit
makefiles to see what other files have been left out.

However, the issues surrounding Unicode support have been looked into so we know
what we need to do, and have some header files ready to use containing appropriate
type definitions. Just about every file in wxWindows will need changes, due to the
pervasive nature of characters and character arrays. Unicode support is needed

<h3>Can you compile wxWindows 2 as a DLL?</h3>
<H3>How can I reduce executable size?</H3>
You can compile wxWindows as a DLL (see above, VC++/BC++ only at present). You should also
-compile your programs for release using non-debugging and space-optimisation options.<P>
+compile your programs for release using non-debugging and space-optimisation options, but
+take with VC++ 5/6 space optimisation: it can sometimes cause problems.<P>
Statically-linked wxWindows 2 programs are smaller than wxWindows 1.xx programs, because of the way
wxWindows 2 has been designed to reduce dependencies between classes, and other
will shrink to a mere 250KB. With this sort of size, there is reduced incentive to
use DLLs.<P>

-<H3>Will wxWindows be compatible with MFC?</H3>
+<H3>Is wxWindows compatible with MFC?</H3>
There is a sample which demonstrates MFC and wxWindows code co-existing in the same
application. However, don't expect to be able to enable wxWindows windows with OLE-2
functionality using MFC.<P>
+<H3>Why do I sometimes get bizarre crash problems using VC++ 5/6?</H3>
+
+Some crash problems can be due to inconsistent compiler
+options (and of course this isn't limited to wxWindows).
+If strange/weird/impossible things start to happen please
+check (dumping IDE project file as makefile and doing text comparison
+if necessary) that the project settings, especially the list of defined
+symbols, struct packing, etc. are exactly the same for all items in
+the project. After this, delete everything (including PCH) and recompile.<P>
+
+VC++ 5's optimization code seems to be broken and can
+cause problems: this can be seen when deleting an object Dialog
+Editor, in Release mode with optimizations on. If in doubt,
+switch off optimisations, although this will result in much
+larger executables. It seems possible that the library can be created with
+strong optimization, so long as the application is not strongly
+optimized. For example, in wxWindows project, set to 'Minimum
+Size'. In Dialog Editor project, set to 'Customize: Favor Small
+Code' (and no others). This will then work.<P>
