The MouseModels module is not supposed to be installed in CPAS 1.1. Unfortunately, it appears the Unix tar.gz and the manual install .zip file for Windows mistakenly had this module enabled. We have corrected the manual install files on the download site so this won't happen again.
If you already have CPAS installed, it should be an easy fix. Go to the "cpaswebapp/WEB-INF/classes/cpasProperties/modules.properties" file and comment out the MouseModels module by pre-pending # to that line. It should look like this:
#MouseModels=MouseModel.MouseModelModule
Restart Tomcat, and CPAS will ignore the MouseModel module entirely. Sorry for the inconvenience.
