Copied from community message board:
A large html file with unclosed <style> tag becomes unresponsive:
I opened a fairly large (50k) HTML file with an unclosed style tag in the <head> section on IDEA 7.0.1. Once the file was open each character typed in the file took seconds to appear, until I managed to close off the style block.

The file in question contains a large <table> construct.

Actually editing the file with the style block closed is responsive but a little slow.

I attach CPU snapshots and a test file that causes the problem (mytest.html) for you to be able to test.
