Graphics Problems

Hello all,

I have a program that uses graphics exclusivly for the GUI and I have one minor
problem. Im using DIBSections for the imagery and double buffering the images
with memory DC's so I can bitblt the images to screen when needed at certain 
locations. What Ive found is in 256 color mode the screen and images retain 
their respective palette until my window looses focus.

I have this short piece of code that works fine for any window that may overlap
my window but if any window  is exclusive to the screen size (full screen) and 
recieves focus then my window losses its palette when it regains focus.
  
    elsif iMsg = WM_ACTIVATE then
   
          if LOWORD(wParam) =  0 then
             hdc = GetDC(hwnd)
             savedDC = c_func(xSaveDC,{hdc})
             ReleaseDC(hwnd, hdc) 
          
             
          elsif LOWORD(wParam) =  1 or LOWORD(wParam) =  2 then

                if lParam = hwnd then
                   ShowWindow(hwnd, SW_SHOWNORMAL)   
                   junk = c_func(xRestoreDC,{hdc, -1})
                   c_proc(UpdateWindow, {hwnd}) 
                end if

any ideas?
