MUI issues

Two more things:

a) I am not able to exclusively select a checkbox using
the GROUPS flag. This works with radiobutton's not checkboxes.

b) I used the "setting environment variable" script
[WriteEnvStr.nsh] in the archive. It worked fine initially
but when I started MUI I always had the installer hanging
at that call. On a hunch I moved the !include before the MUI's
!include [at the top of the file]. It worked perfectly after
that. Is this is a known issue?

Thanks. Regards,

Only radiobuttons can be exclusive. To make checkboxes exclusive you have to program them to work that way.

Any warnings when you include it after MUI.nsh?
