So far i really like playing the game, BUT i seem to be one of the few persons that still play on a 4:3 monitor with the Resolution 1280x1024 in fullscreen mode.
I just cannot click the "Back" Button on the left, because it is not shown on my screen. When i switch the resolutuon to 800x600 and window mode i can see and click the button, but it is really annoying! Creating decks is just awful this way, tho it should be fun ;) I have the same issue when choosing the cards in Dungeoneering Mode. It is not possible to see the left stat (Attack/Gold cost) of the most left cards.

In short:

• UI does not resize properly (1280x1024 fullscreen, 4:3 monitor)

Suggestion:
If resizing is not possible, perhaps place the "Back" button on the bottom instead of left, like it is in other parts of the menue.
