Trish, I personally tend to avoid the Layer Styles for a few reasons:
– the settings are completely non-intuitive and the Size, Opacity, X and Y values don’t resemble what they are in the “menu commands”. For example, the Size in the Layer Style means the Blur in the Drop Shadow. How would you make sense of that?
– the settings have changed throughout PSP versions, where in older versions, the Size was based on the image size so the same element on a different canvas using the same settings would have different results. So it was too inconsistent to give valid instructions.
– the X and Y are not measured in pixels but in proportion, making it very inconvenient.
I will try to use it if I HAVE to apply an effect to a vector layer, but it am often still not happy with the in-flexibility it gives. Sorry to be a downer, but to me, it is not a feature that is intuitive and convenient enough to use most of the time.
