Hi,
I'm trying to create a custom folder containing all the toolbox parts our company uses. In the toolbox configuration window I've copied the entire contents of the GB standard and moved the parts into folders that I find easier to use.

However I've encountered a strange problem. Some of the files (particuarly hex head bolts) have disappeared.

They still appear in the browser, but their preview image is gone to a default, and I can't do anything with them (modify or use in assembly).

The Filename box is highlighted red and when I hover over it, it says "Error, no path in file name".

Does anyone know why this is happening, and how to fix it?
