Check Box, Option Box and Frames transparent

It's a class that converts opaque CheckBoxs, OptionBoxs and Frames to TRANSPARENT!. Easy to use, very effective. It can be used with other controls with properties .hwnd and .backcolor . There is only one error: blurred fonts doesn't work fine with the transparency function. Sorry for my bad english!. Comments are welcome! Thanks to GioRock for the tip. I forget to say: the clickeable area will be the non transparent region.
