Sounds like the tablet locked up/crashed... don't know if it happens again do share but I haven't run into that at all... can anyone else confirm/deny this happening for them?

The seconds actually adds almost zero load to the CPU as I made it really efficient in the way it redraws things (and like all else it stops drawing when the tablet is inactive), but if it's bugging you there are two options: you can disable it globally (for all themes that support it) by editing your preferences file:

1. edit /home/user/.flipClockPrefs.xml
2. Under <mainOptions there's a tag that says showSeconds... change the 1 to a 0
3. Save, re-run flipclock. Seconds will no longer be drawn

There will be a preference setting for this on the "clock-settings" screen when I get it made.

The other alternative, if you wanted to disable it for just a given theme, is to delete the "Second ticker" image from the theme path; Flip will detect that it's no longer present and so won't try to draw it. The file for the day theme is:
/usr/share/flipclockC/themes/defaultFlip/secs.png

I mentioned this in the other thread but must have missed it here. The way app manager works is that it will NOT automatically pull dependencies from repositories unless the package you're installing is in Extras or Extras-devel. When I manage to get a package that willbuild with autobuilder and make it into extras, then the manual sdl_gfx stuff won't be needed as the dependencies will be pulled automatically; you guys are just all getting in for the "preview" ahead of time, so you have to do a bit more leg work as a result ;-)
