Re: refresh issue with QLPreviewPanel..!

Needless to say that what you do is totally unsupported and will totally break in 10.6. 10.6 now provides a public (incompatible with Leopard) API but even with this API, what you do is greatly unsupported (and will break in the future). Add to that the fact QL panel is very asynchronous, and it's
