Amaya crashes

Hi,

With Amaya 8.5 on Windows XP, I encounter a problem with the
attached files.

I open « test.htm », go to change document doctype to HTML 4.01 strict.
Then I ask to view the source code (Ctrl U - Ctrl U).
Amaya freezes.

I do not understand what is happening.
What does Amaya dislike in the page ? Anyway, it should not crash.

Incidentally, the menu in CSS is not well rendered.

Best regards,

Julien
