Freezing on Win7 Home Premium x64 with Flash Player 11.5.500.85
I have the same browser freezing problem with both 11.4.402.278 and the 11.5 beta on two identical HP DV9700T Laptops running Windows 7 Home Premium x64. Loading pages with flash cause the browser to hang. If I kill the flash process the browser resumes. Note: When I am on a page with flash there are two flash processes in TaskManager. I am using FireFox primarily, but the same freezing behavior is observed in IE. So far, in IE, I have only seen one Flash ActiveX process. Significantly older versions of of Flash work fine.
Both systems have AVG Free edition. The problem still occurs when I "Temporarily Disable" the realtime scanner. Both systems have nVidia video cards.
When it freezes the cursor behaves normally, just the browser window is 100% unresponsive. I can ctrl-alt-del to bring up task manager or I can use the Windows Flag (start)->Run (yes, I have "run" manually turned on in my windows 7...I can't operate without it.)
Both systems have HP All in One Printer drivers installed as well as: Office 2007, Media Player Classic Home Cinema set to default for all media types, 7-Zip, Adobe Reader, CCleaner, Spybot S&D, CDBurnerXP, Corel Paint Shop Pro X2 (12), Java, .NET, Various Visual C++ Runtimes, iTunes. Those are all the common software programs.
Here are my system details in two different formats::

This problem has existed with the last several versions of 11.x and it has become extremely cumbersome. Let me know what other details you want.
