Launching the application takes a considerable number of minutes more than on Windows. Took at least 3 minutes to get the application initialising screen and several more until the main application appears.
Once the application loads opening a tree works and switching between views is possible. Adding media, facts and tasks works as expected. Creating a backup of the tree also works.
What does not
Selecting a different person in the family tree (or from the person index on the left side of the family tab within the people view) causes `0009:err:seh:setup_exception_record stack overflow 120 bytes in thread 0009 eip 7920cd3c esp 002312b8 stack 0x230000-0x231000-0x330000` requiring the process to be killed.
To navigate to another person select the person tab within the people view and navigate using the tree at the top of the window.
What was not tested
Online functionality was not tested. Creating a new tree or using the export option to export the file in another format.
