We have our toolbox set to create a copy of the part (bolt, nut, whatever) to a common folder called 'ToolboxCopiedParts'

When opening assemblies I occasionally get warnings stating the component is not found, so I click OK and wait while it does something

I looked into it recently and sure enough the part does exist, the path is set to look where we keep the copied parts, but I still get the error msg

Any ideas?

Here's the message...

here's the component, just where it should be looking
