Toggle show system/hidden files not working with Windows 7

Hi, the command 'Set HIDESYSTEMFILES=Toggle' works everywhere except when the lister is focused on a Windows 7 library. In this case it always shows me hidden files and I cant toggle it off.

Thanks for any help.

At the moment Libraries are handled by Explorer so the Opus options don't affect them. Changing Explorer's hidden files/folders setting should, though.

Thank you. Problem solved.
