Cursor Bug
There is a cursor bug that can:
Cause the mouse buttons to not do what you expect; or
Cause a transparency problem with the cursor; or
All of the above
To work around this, edit the rise2.ini file (~/.wine/drive_c/users/{user}/Application Data/Microsoft Games/Thrones and Patriots Trial/rise2.ini) and set "ForceGDICursor=1".
