Are all of the clients (GM and player) using v3.3.7 when it crashes? Or are only some on v3.3.7 and others on v3.3.6?
The full panel is made mostly for face to face play, since it obscures the other panels, like sidebar, chat window, modifiers, dice tower, etc. . It can be used in a regular game by toggling between the smaller and larger panel when needed. With the current architecture, the full panel can not be placed under the chat/modifiers/etc, because the current version of FG requires images to go to the edge of the screen, And that would make portions of the map unable to be seen or interacted with.
