Machine:

Lenovo W500, Dual Core 2.53 vPro, 4-Gigs Memory

OS:

Windows Vista 64-bit Business

 Visual Studio:

Visual Studio 2008 (9.0.30729.1 SP)

Step To Reproduce:

1. Create Web Project
2. Open Markup Editor on Default.aspx
   
3. Add <link /> to a stylesheet, or add a style block.
   
4. Continue editing Markup for a few seconds.
5. Visual Studio Completely Locks up. Have to kill process.
   

 It just locks, it does not consume CPU.

I do not see this at Work running XP Pro 32-boit, or on my other laptop running XP Pro 32-bit.

 Please, if any of you known of a solution to this I would really appreciate it. Currently I am getting around it by adding the link to the style sheet in the code behind when it renders. But this is not ideal at all.
