Inconsistent Document Recognition for Syntax Highlighting

Here's something strange.

When I run CFBuilder and open a cfm or cfc file from a project, the text is NOT colored. One file or multiple -- nothing. No code folding either, for that matter. However, if I leave a few files open, quit Eclipse, and run it again, the FRONTMOST file is properly highlighted, code-folded, etc. But the other open files remain unrecognized. Another datapoint: new files created via New -> ColdFusion Page are also NOT recognized.

This is on Mac OS X 10.6, in a fresh installation of Eclipse 3.5, with a fresh installation of the release version of CFBuilder, in a new workspace, with no other plugins except subclipse (also freshly installed).

Anyone have any ideas?
