My build is :
XAMPP 1.6.2 (Apache 2.2.4, PHP 5.2.2, MySQL 5.0.41)
The XAMPP is supporting a bunch of other PHP code, so Silverstripe lives under an httpd.conf Alias ... redirect. This seems to require a RewriteBase statement in SS's .htacess.
Most of TinyMCE editor functions, but on attempting to insert either a symbol, table or anchor, we see an alert panel: "Undefined".
I thought it might involve some Ajax, and perhaps the RewriteBase hack might be interfering, but the lack of Apache log entries kills that theory.
Any clues ?
