Most of the time the application works but occasionally it freezes and will not work when an event happens. It will show the event but when I click on it, nothing happens. Sometimes it flashes an error message before freezing. I have copied the error message which I am attaching as a file.
GGerror.txt

Can't confim that error. I will release a new version later. Pls test it and give me a report, if the error still exist
