ga2000gt, You don't see hidden content in forumdisplay even if you thanked or replied? Is that what you're saying?
That's the way it works, because to simply hide the content is about 100lines less code, that's why hidden content is only available where it needs to be shown (showthread, showpost, printthread).
No preview is intended
same thing for newthread/newreply; you know what you're intending to hide whilst typing I guess, and because of the unfamous bunch of messie code wysiwyg produces once in a while it's easier to just not parse hide in any editor

no, when i hide the content i can't see the preview, and when i do not hide, i can't see the preview neither :S
so.. the problem is when the hack is enabled, i can't see the preview, but when i disable your hack, i can see it
