Issue with the GanttProject scale

This came by email

I have a problem with GanttProject scale. The scale is so small that I can’t find the settup putton where I could change the scale to larger. Is there any keyboard commands how I could change the scale?

I am not sure that I clearly understand the issue, but I guess it is about the font size on high-resolution screens.

You can change the DPI setting by editing GanttProject’s configuration file. The file name is .ganttproject and it sits in your user’s home directory. Open it in any text editor, find this line:

   <option id="ui.screenDpi" value="96"/>

and replace the value with e.g. 150

You may also try using GanttProject 3.4 Beta which automatically scales pretty well.
