Could you take a look at the troubleshooting FAQ and follow through some of the suggested solutions. We'd like to get more information from you. The FAQ covers how you can create a bug report and the information we'll need.
I also branched your issue out to a seperate thread because it wasn't RealPlayer specific.
Java 7 update 5 has been just released, thanks for replying.
I did not install it though, in order to try to reproduce the problem.
I am a Mechatronics Engineer and I have a non-common OS and software configuration.
There is a numerical simulation application in my system which requires a programming language compiler to run, and such compiler requires the OS primary SDK and framework to be "understood" by the system.
That said, I believe all the debugging routines might be somehow limiting FlashPlayer abstraction layer functionalities.
As awkward as it may seem now, Firefox did not crash after one absolutely random measure I took.
I opened this page: http://www.adobe.com/support/flashplayer/downloads.html and downloaded Windows Flash Player 11.3 Plugin content debugger (for Netscape-compatible browsers) from this link: http://download.macromedia.com/pub/flashplayer/updaters/11/flashplayer_11_plugin_debug.exe.
Although there is a hanging before opening the about page and Youtube, flash content is indeed presented.
Well, there might be a different abstraction layer approach regarding this content debugger version.
I wait for further insight from you guys.
