Editing aspx/ascx files randomly disabled in Visual Studio 2010?

Question

I\'ll be debugging a site in Visual Studio 2010 and editing an *.aspx or *.ascx file, and without warning, it will lock up so that I can\'t edit it

Answer 1

I can tell you it is known bug. It always happen when you edit on CSS or Javascript in Code View.

I have report to MSDN forum and Microsoft Connect, but it seems it is rare bug,so not many people to solve that.
