MMgWjo:

First, check to make sure you have the latest "build" of BIAB, i.e. 381.

- when you say "i'll go to SelectStyle", I assume you mean the "Style" button on the left-hand side of the menu bar. When you "mouse over" it, it says "Styles Button".

- when I click on that, it opens up the "Select Styles Prototype Style = ..." window, showing in the top left-hand corner.

- the prototype style shown there, will be the last one you selected (possibly SPICE_W.STY).

-However, when you select your target style, =C_CLAYG.STY and click on OK, when the window closes and puts you back onto the main screen, your new style will show in the very top left-hand corner, as well as in the the box next to the "Style" button.

Let us know if that's not the problem.
Mine works as described above.
If yours doesn't, perhaps a "Return to factory settings" may be required.

Good luck!
