No work copy or paste with Windows Live Hotmail, in Safari

I have an iMac with Mac OS X Lion fully updated to the latest version 10.7.2, I use Safari for the internet, also updated. The case is that for a week or two in my Hotmail, when I press Command + C for copying some mail I get an error message:Hotmail I can not complete this application. Microsoft will contact you in relation to the errors that report.Happens to me for copying Command + C to paste with Command + V. I always get the error that I have set above.I sent the error to the Support Center Windows Live Hotmail, and have told me that I contact Mac support, and here I am, to see if we can figure out from where the fault.The tests I've done has been copied and pasted in the following browsers:- Google Chrome: failure like Safari, get the same error.- Opera 11.60: working properly- Firefox 9.0.1: works correctly.I thought it might be a bug of WebKit, the engine of Safari and Google Chrome, as the failure occurs only in these two browsers.But the Hotmail Support Center, tell me no, that goes right to them.The error you can see it recorded here (Spanish):

I have also recorded the error in Google Chrome (Webkit Area) (English): http://code.google.com/p/chromium/issues/detail?id=108808

Furthermore, failure sent via Safari, Send Bugs to Apple.But I would like to know that I do to get my mail usually works, as I need to copy and paste text in the mail and will not let me in any way.I spent a video with the error that happens, you can see it here (the error message comes out in Spanish):

I hope I can help fix the bug that is happening, or see if you can fix Apple Safari.

Note: Safari Version: Versión 5.1.2 (7534.52.7)Thanks in advance.
