Haskell Communities - Inline .pdf problems

Dear all, there seem to be some problems with displaying the .pdf file inline with IE and Acrobat plugin. I've got no idea why (any PDF experts here?-). The file seems to be okay, just save to disk and open (in fact, when you first save it to disk, the inline display has been seen to work properly immediately afterwards..). [I've tried optimising the PDF for web-display, but that seems to be even worse; I guess the file is just too long for inline viewing?-] Claus
