SPi-V 1.2.14
SPi-V 1.2.14 (the current version available for download) fixes a long-standing bug that slipped my attention.
On certain ATI-based systems (mostly macs like the mac mini and iBook G4), all uielements would disappear at certain widths. I didn't notice it because I apparently always opened my Safari window at a width that 'works'. It should be fixed in 1.2.14. If you are still not getting uielements when you expect them, please let me know (ie: no progress bar, no field of view branding when on the free version and no overlays when you press 'a' or 'd').
SPi-V 1.2.14 removes the workaround I had in place for OS X 10.4 Tiger rendering the content too heigh. The fix was having some more unwanted effects than I would have liked.
