When you run Stylemaker for the first time, it will attempt to bring up the developer's terms for agreement. However, this window is too large and there are no scroll bars. On many desktops, it will go off the screen.
We are aware of this issue and it will be resolved in a future version of Stylemaker.
In the meantime, when the agreement pops up onto your window, just tap the enter key. The "agree" button is highlighted by default, and only needs to be selected. You will then be taken into Stylemaker.
