John,
Sorry that you are seeing this issue.
Can you please give us some more details?
1. Is this a standalone Angular IDE installation or did you install CodeMix on top of Eclipse? If Eclipse, then please share the version details from Help > About Eclipse dialog.
2. Are you seeing this problem recently? Did it work fine before? Any recent changes made to the IDE or the machine?
3. Is the engine connected? You can hover over the icon besides CodeMix in the bottom left for the engine status.
4. How about a new workspace? Do you see the same freeze in the new workspace as well?
5. Please share the .log file located at workspace dir/.metadata/.log (rename the extension to .txt and attach it here) for further investigation.
Apologies for inconvenience caused.
