Relative XREF paths

Bonjour, we are preparing procedures for DWGs storage for long term projects. We sometimes hear about difficulties or bugs about using relative paths Actually from Autocad users... After having checked Bricscad forum about this issue, we found old bugs traces.Question: today, are there some limitations, risks, or bugs related to relative path usage? At Intellicad level? At Bricscad level? at DWG level? At Windows level?Thanks on forward
