I have a simple Matrix field that includes two sub-fields: a one line plain text field, and a multi-line plain text field. When I try to create an entry Craft freezes at the Create New Entry screen. When I run the same Craft configuration on a remote apache server no freezing occurs. I'm using a wamp server (on a PC of course). I have the same problem on my wamp-craft setup on PC at work and my PC at home. I've never had a problem with any wamp server before and have never had a problem with Craft. My guess is it's a wamp permissions problem that's specific to the Matrix field (this is my first attempt at using the Matrix field feature). Any suggestions?
craft/storage/runtime/logs
or in your WAMP/Apache error logs?
