I have AVG installed on my main system, but I don´t have any AV installed on Win 7 beta setup or actually anything else much (but I´m about to install some benchmarking utilities to test it thoroughly

). What I reported with the .pfd-s opened in multiple tabs in IE8 happened actually after I had reinstalled Acrobat Reader v9, updated it and uninstalled Adobe AIR and Adobe.com to try out how it would be going with the updates installed. I´ll try it the other way around - installing Reader, removing AIR and .com and installing the updates. But I doubt that this would change anything for me...
BTW, when I close IE8 with a .pdf not opened in one of the tabs and the error message from Adobe, Win 7 gives "IE8 stopped responding" -> sending a report -> details: it´s referring to the Tmp folder... I also checked event log and it is massively full of errors, but that´s probably because of the beta. I found a few referring to DHCPv6 at the same time as Adober Reader acted up, so I "disabled" IPv6 (everything of it) by registry and rebooted, it seemed to have made things better, but not entirely... I´m afraid the problem is probably more complex than apparent. Since Acorbat Pro is reported to be properly working with IE8, I wonder what is missing in Adobe Reader to do so as well...
Cheers,
