Page designer - Refreshing designer

Hello Mike:

Thank you for your response.

In the past few days the page designer crashes when I change from code view to design view. But today works fine. I've tried to put a Tile Manager control into a Border Layout control and remove some text that the Border Layout put automatically.

My browser is Chrome 41.0.2272.118 m version.

The code is:

If I discover the exact point when crashes I'll write to you again.

Thank you.
