Where are you looking for it in StylePicker? In the Windows version, it should appear in the "Other Styles Found" category.
Also, can find the actual .STY file on your computer? Are you saving it to the main BIAB folder? Or in the BIAB/Styles folder? Only styles in one of those two folders will show up in the StylePicker.
The styles are not in the stylepicker. In the mac version no "other styles found". I do update the stylepicker, but nothing to see...
I do save in the BIAB/ styles folder.
I find the style on my computer (Finder/BIAB/styles).
When I double click on the style. "Something" is applied, but not at all what I saved.
