If incorrect fonts are displayed in the 3D scene of IPO.Log, this may have something to do with the graphics setting.
It is important to always use the latest graphics driver. If this does not solve the problem, IPO.Log 4 Workspace can be started without textures.
There is now a way to simplify the 3D rendering.
Therefore IPO.Log Workspace must be started with a separate start parameter.
The easiest way to do this is to create a new shortcut.
Just right click on the IPO.Log_4WS.exe application. There a shortcut to the desktop can be created via "Send to".
A start parameter can now be specified by right-clicking on the new link and "Properties".
Please enter "-notextures" in the "Target" behind the path to IPO.Log.
After that you can start IPO.Log 4 Workspace without extended 3D textures.
