Folder Options are not applicable to the special Recycle Bin folder and you should not be able to open the Folder Options dialog at all when you are in it.
The global filters make it easy for people to make an Opus wide setting that affects all Layouts, Styles, folder formats, etc in a single change since the global filters get priority over the folder options/formats... whereas making a similar change to each individual one of those same mechanisms can be a burden if you have many defined.
Either way, if you mean the "$Recycle.Bin" folder at the root of a hard drive... all I can say is that making a change to folder options to hide H +S attr items works fine here. No need to go to the global filter in Prefs just to hide that. You may have a folder format for a top level folder (or 'all folders') that is getting in the way of whatever you try in folder options? Go to C:... then open the Folder Options dialog. Put a check in H and S in the Hide Filter section, apply it, and you should see the $Recycle.Bin folder disappear. Works here...
Good point from Steje. I assumed we were talking about when you are inside the Recycle Bin folder. If we're actually talking about being in C:\ and seeing the $Recycle.Bin folder (related but different) then what Steje said applies and you can ignore most of what I said.
I did the filtering on C:. I now see that if the global sare set to "Show", Folder Options work on the lister but not the Folder Tree.
I can check Hide S and H fine, and the Recycle bin disappears in the lister. But when I click on another folder and then back to C|, the Recycle bin in the lister appears again, the the Hide S and H have been unchecked.
