Lost toolbar after minimize

[toolmanx]

I'm running AMD Xp1 compiling with Borland bcc32 with cpp
extensions.

When I minimize and then bring my window back up to normal, the
buttons in my toolbar disappear. I can bring them back up to
the top by doing a resize (mouse on edge of window with a
button down), or by opening the system menu and reclosing it.
I can also fish around at the location where the butons are
and a mouse button down will force the buttons to the top.

I've tried a SetWindowPos() with HWND_TOP and HWND_TOPMOST to
try to force the buttons to the top of the "Z" order. That
didn't work. Since the bar the buttons run on always shows, only
the buttons disappear, I'm guessing changing the "Z" order of
my toolbar window is not the answer. I think my toolbar itself
is O.K. Any ideas as to how I can keep my buttons showing?

I hope I can get an answer without sending my source code. It's
getting pretty big. I'd have to insert the whole file as a file,
otherwise I'd fill up too much thread space.

I have my toolbar code in a function and call the function
from the Create case.

case WM_CREATE:
            {
             CreateToolbar(hwndMainFrame);
             GetClientRect(hwndMainFrame, lprect); 
             InvalidateRect(hwndMainFrame,NULL,TRUE);
            }
                break;
