uncheckable radiobutton?

I have these 2 options in my installer that i dont want to be installed together

so the options are

install #1
install #2
install none

but using radiobuttons like so:

Function .onSelChange

  !insertmacro StartRadioButtons $1

    !insertmacro RadioButton ${MAPTEXTURES}

    !insertmacro RadioButton ${MAPTEXTURESLOW}

  !insertmacro EndRadioButtons

FunctionEnd

... makes them ununcheckable (see that double negation?) once checked..

It would be easier to include a dummy Section that does nothing and include it as a radio button.

is there any way of figuring out what checkbox that had it's status changed in an .onSelChange?

No doubt it's possible but nobody has bothered trying to get it to work. You'd need to create your own version of the RadioButton macros set.
