as explained in the online help I selected on the left "Load in the first frame" (I'm not shure if this is correct because I'm working with a German version) and selected on the right "Load in the second frame". Then I made a double click on the second file and got two times an error message:
The file or directory 'AbstractMeasurement.cs' does not exist. Please check the file or folder names or the commandline parameter.
It seems for me as UC would try to load the files not from the displayed folder but takes the file names as absolut pathes. But I can't see any setting to change this.
Does anybody has a suggestion for me what to do. I'm using UC 5.10a Prof.
