I think my bitmaps got corrupted somehow. After copying a backup of the image files the WPS is working now, as for the SBS I will keep looking it is probably something similar
SBS fixed as well though I am still having a couple of issues:
1. in the sbs if you scroll towards the top of the list it jumps down then back up? i'm not quite sure how to describe this, is there anything i can do to fix this?
2. in the wps I display different viewports if the screen has been touched. Once the timeout is reached the screen flashes black, it didn't used to do this, is there a fix? I guess this is because i am drawing over the cover art.
* note that those empty viewports are to provide a black bar at the top and bottom of the cover art and make no difference to the behaviour of the wps
* rename file to .zip to open
