Even with the new version, web pages that I'm working on hang all the time (both Firefox and Chrome). Sometimes my recorder window and page no longer seem to be in synch and stop responding to each other. The potential for this is great but making this tool solid should be top priority. Edit: I didn't see where to reply to your message, but yes, I have 3.5.7, downloaded the latest just today. I'll log issues. Thank you.
