Enlarging the cards in my hand (shown on the bottom of the screen) by hovering the mouse over them and using the ALT key works only if not zoomed in on the game table too much. If I use the mouse wheel to zoom in on the game table there is a certain point at which enlarging the cards in my hand using ALT does not work anymore. This is obviously nonsense and should be fixed!
EDIT: This only happens if the camera is tilted. If the camera looks straight down on the table ALT-zooming the hand cards works at any zoom level.
