--- Comment #2 from Guillermo Reisch  ---
Breakpoint 1, Control_DoLaunch (panel=0x86fb34, hWnd=0x30054, wszCmd=0x242b62)
at dlls/shell32/control.c:821
821             if (!applet->proc(applet->hWnd, CPL_STARTWPARMSW, sp,
(LPARAM)extraPmts))
Wine-gdb> next
824             Control_UnloadApplet(applet);

FlashPlayerCPLApp.cpl respond to signal CPL_STARTWPARMSW returning TRUE (if it
handle the signal correctly), but not show a dialog box at all!
if line 821 is comment and force the signal CPL_STARTWPARMSW (line 822) then
dialog box is show and work. FlashPlayerCPLApp is not handle CPL_STARTWPARMSW
correctly...
