I've had no trouble creating multiple windows for a single app - you
must be doing something wrong.  A few possible problems:

1) You don't need to do a MakeProcInstance on a window function - 
   only on a dialog box function, a window subclass function, or
   some type of callback function.

2) Set palclass.lpfnWndProc to PalWndProc (just like the class 
   structure for the main window sets lpfnWndProc to WndProc).

3) Make SURE you export the PalWndProc function in your .DEF file.

4) You may want to force a WM_PAINT of one or both windows after 
   you create them by adding an UpdateWindow (hPaletteWnd) or
   UpdateWindow (hWndApp) call after the ShowWindow call for the
   appropriate window.

That's all I see or can think of offhand.  There may be something 
else, either in code that you didn't post (like in the window
function for the palette window) or that just escaped me when I
read over the article.

Good luck -
