If you type white-space: <attribute> within a CSS section of code, it doesn't highlight the white-space property and doesn't give you the code-assist drop down menu like other attributes...

It's a valid CSS attribute. Not sure if there's others like that one, but this is one I found.

Is there a way I can update this myself or is it ann encapsulated into dll's?

as of version 5.2, it works fine:

I think I understand what happened...

I was missing a semicolon after an attribute above the white-space one, and it didn't highlight because of this, then I thought it wasn't supported so I added the word white-space in the Reserved Words list for CSS and that changed the highlighting color to black... I reset the Reserved Words list to default after correcting the invalid semicolon and now it's fine.

Sorry for doubting

By the wya, PhpED is the best IDE I've seen in a VERY long time... beats all the others I get. Once our trial finishes I'll be nagging my boss to buy it!

Cheers!

Thanks for your kind words!
