Windows 7 + System Flash
This applies to Windows 7 and MXWendler version 4.2 and above
If you use MXWendler in Win7, or Flash > Version 9, you'll notice that system flash doesn't work.
1. Flash.ocx is not found
2. You installed flash, but using Firefox
Install Flash, but install it using the Internet Explorer
Firefox installs a private plugin .dll, Internet Explorer installs a system-wide ActiveX control ( which is used by mxw )
