Toolbar button stays pressed (win32)

RaduV (6)
When I click and drag a toolbar button it stays pressed when it should be unpressed when I release the mouse. How do I fix this?

probably you are losing some windows messages. Show some code.

Here is the code to create the toolbar and add buttons. Window procedure is only handling WM_DESTROY.

HWND CreateToolbar(BOOL flat, HWND parent)
{
	DWORD styles = WS_VISIBLE | CCS_NODIVIDER | CCS_NOPARENTALIGN | TBSTYLE_TOOLTIPS | TBSTYLE_WRAPABLE | WS_CHILD;

	if (flat)
		styles |= TBSTYLE_FLAT | TBSTYLE_TRANSPARENT;

        HWND hwnd = CreateWindowEx(0, TOOLBARCLASSNAME, NULL, styles, 
		CW_USEDEFAULT, CW_USEDEFAULT, CW_USEDEFAULT, CW_USEDEFAULT,
		parent, NULL, GetModuleHandle(NULL), NULL);

	SendMessage(hwnd, TB_SETEXTENDEDSTYLE, 0, (LPARAM)TBSTYLE_EX_DOUBLEBUFFER | TBSTYLE_EX_DRAWDDARROWS);
	SendMessage(hwnd, TB_SETMAXTEXTROWS, 0, 0);
        SendMessage(hwnd, TB_BUTTONSTRUCTSIZE, (WPARAM)sizeof(TBBUTTON), 0);

	return hwnd;
}

{
    TBBUTTON btn = { image, idcmd, TBSTATE_ENABLED, (idcmd < 0? BTNS_SEP: BTNS_BUTTON | (dropdown? BTNS_DROPDOWN: 0)), {0}, 0, (INT_PTR)tooltip };

    SendMessage(toolbar, TB_ADDBUTTONS, (WPARAM)1, (LPARAM)&btn);
    SendMessage(toolbar, TB_AUTOSIZE, 0, 0);

Has anyone here ever made a toolbar in win32? Because this seems to be their default behavior. i've known about this thing for a long time but ignored it. It's easy to reproduce but not likely that anyone will accidentally: right-click and then left-click a toolbar button, drag outside of the button then release both mouse buttons and the toolbar button remains pressed. You have to click the button again to have it unpressed. It happens with or without visual styles.

Nobody huh? This is so annoying because other windows applications like wordpad don't have this bug so either i'm doing something wrong or there is something i'm missing.
