Running Slicer 4.8.1 on Windows 7.

Created a new fiducial list with “&” in the title and saved as .mrb file. I can keep working on the file without issue as long as it is not closed. When trying to reopen the .mrb, all data is missing even though the size is ~100mb. I’ll avoid special characters from now on, but just wanted to point this out.

Thanks!

Thanks for reporting this. The issue has been fixed a couple of months ago. Any ASCII characters can be used in node names in recent nightly versions.
