I had to reinstall GUI-O live Designer (v.0.0.7) without problems. I can edit widgets, change their characteristics but when I want to save or load a file, an empty window (windows explorer) opens for ~4 seconds then the application closes. I am connected with Tcp-Ip,
Is it possible for you to send the design file (.gdf) to email@example.com? So I can test this.
There were some changes (in one of the previous versions) regarding the saving / loading, but old design files should be compatible with newer versions. What was your previous version (before the upgrade)?
