If you find an app that's not compatible with Lit, you'll know because as soon as you click the app's menubar item while Lit is active, Lit will close and the application will not become visible. In that case, launch Lit, then the incompatible application, and do the following:
Open Console (found in /Applications/Utilities) and look for a recent entry corresponding to the application. It should look like "Lit: Terminating for switch to Bundle ID:". The Bundle ID will likely be something similar to "com.company.application".
When you find the correct entry, Contact Us and copy and paste that entry into an email. Make sure the Bundle ID is in the email. I'll add the program to the incompatibility list and check back with you to ensure it works properly.
