Unexpected error occured whenever I click on a field for text input in tables

I've recently installed a copy of COMSOL 4.2 on Mac OS 10.8.5. The program runs fine except that an error message would pop up whenever I need to edit a text field in a table, such as parameters and variables. However other text fields are fine, such as the blanks you need to fill for various variables in the modules. For now the solution I have is to edit those tables in a windows version, and transfer the model file to my computer and run it.

Please see the last section of the log file as follows. As is indicated by the error message, which says un expected error occured, the detail of this error can be found at the end of the log file. However I'm unable to decypher what the log file says.

I would really appreciate any help with this.
