Aha brilliant! Okay great thanks AndyM, that confirms it was the problem I thought it was, I've fixed it in SVN. I'll put another update package/preview release together in the next few days once I sit down and spend some time fixing up/tweaking the graphic issues. In the mean time if you're getting annoyed by that digit thing and can't wait, just save the attached image as "10.png" to /usr/share/flipclockC/themes/defaultNight; that will solve the problem for you.

I'm going to have another go at the packaging thing this time around too, as it seemed to work before but I still never saw any sign of 0.9.x showing up in extras-devel, despite autobuilder reporting everything was good and worked properly...

As an update, here's what I've been tweaking:
- Sounds are now faded in over 60 seconds, at 20 steps of +5 volume each.
- There is a MAX alarm sound setting in the config file that works, I just haven't made the interface button to change it yet.
- Complete rebuild of Insomniac mode; there's now a config file setting to control how dark/bright insomniac mode is, and this gives you the same full range as the "Advanced backlight" app. By default brightness is absolute minimum, lowest possible setting from advance backlight (other than off of course). I haven't implemented the interface button to change/control this setting, but I have tested it working as is. At the default value though the "night theme" clock is MUCH better than it was before for the dark...
- Few other minor tweaks and fixes.

Next up, fix up the graphics and then preview 3 time ;-)
