I have been noticing with some of the latest skins designed for WB4, (including my own) that as each new alpha build is released, something changes in the skin. Usually it is one of the margin parameters and I have to open the skin up and adjust them until the skin looks right again. Sometimes the transparency gets switched off on some bitmaps and I have to go into SS and switch it back on.

All I can suggest to others who might be experiecing similar problems is to be patient. Once the WB4 is in final release then the skins in question can be fixed and uploaded again.

Such is the nature of an alpha.
