I have updated Maul Publisher again, as I have just got myself a new high resolution monitor and noticed that the application looked all ugly and blurred.
It turns out, Ms have introduced some new API with Windows 8 that makes older applications look really ugly. That part is easily fixed, because Visual Studio offers a manifest property to set an application to high resolution, though it did take me an hour to find it.
Then of course other things got broken, in this case the cursors were flickering. So now 6 hours later, there is a new version online. Such small updates are not automatically installed, you have to download and install them manually, or wait for a version change, at which point the check for updates feature, when enabled, will update the application.
