Roland: Thanks for the speedy response! It turns out that the example program basics does the same thing on my target platform. In addition it appears that the problem is related to a GTK+ theme. I happen to be using Aero-ion3.1 theme that has a black background - this is where the problem is apparent. However if I select another theme such as Clearlooks with a light background the scale appears 'the way it should'. I've attached a photo of basics started when the Aero-ion3.1 theme is selected. Hope this helps... snafu > Date: Wed, 15 Oct 2008 20:38:09 +0200 > From: box2OO6 eudoxos de > To: gtkdatabox-list gnome org > Subject: Re: Version 0.8.2.2: Ruler updates 'smearing' > > Hi John, > > since version 0.8.0.0, GtkDatabox comes with its own rulers. > > The old gtk+ rulers have several problems, when ranges are very big or > very small.
