This is a fundamental restriction on the use of WebKit.Yes, I know. I just hoped there was some secret magical workaround which would enable me to create attributed strings in the main thread. The point is I'm trying to create something like Finder's "Show icon preview" functionality, trying to create graphical representations of some text files (which are kept in memory) but to still keep UI responsive if a user wants to scroll view etc.So, I assume creating attributed strings is not thread safe, but I don't remember anything like that stated in the documentation. In my opinion, that looks like a bug.
For what it's worth, it's documented in the Leopard release notes: http://developer.apple.com/releasenotes/Cocoa/AppKit.htmlOn 10.5, NSAttributedString will automatically use performSelectorOnMainThread for you, so if you want to always use a helper app, you'll have to figure out beforehand if it's HTML.
