This problem appears to be filesystem-related, i.e. not to do with comctl32.
For testing, I was running Ubuntu 8.04, with /host being the NTFS Windows (Vista) partition sda2. Wine Z: is Linux filesystem root (/).
/host is readable and writeable; all files and directories there have permissions rwxrwxrwx. It is not possible to restrict the permissions of a file using chmod.
When an uncompressed ADF disk image file is selected in WinUAE, clicking the write-protected checkbox causes WinUAE to try to write-protect the file, which in the case of a file in Z:\host, has no effect. So WinUAE does not allow the box to be checked.
Don't run programs from a windows partition.
