CSS highlighter locks up application

[quartexNOR]

The CSS highlighter, when used with a modern css file, just freezes the entire application.
I have tried to track down where in the code this might happen, but the freeze is so hard that the debugger doesnt even kick in.
I have a hunch that its a matter of new CSS keyword which the parser does not know. I am not intimately familiar with how the highlighter works, but i noticed that it uses a hash based lookup table, which might explain the issue when faced with an unknown keyword, or syntax for a known keyword that has changed in later times.

Right now, the css highlighter cannot be used, which is really sad because it was very useful.

Here is the fix.

Some of the highlighter files look like they were generated by the SynGen tool. i've been trying to find their original sources. Any ideas?
