Imports being lost

[Earl]

Continue to be troubled by referencing issues in this one app. My app
references several external .DLL files that I created. Sometimes when I open
the solution, I get Build errors that "Namespace or type ... for the Imports
cannot be found". Yet if I close without save and re-open, the referenced
..dlls are there and no build errors. Can anyone shed some light on this
"lost reference" issue?

I have seen this with my signing key which I keep on a USB flash drive.
if the drive is not mounted when the project is loaded but is mounted
later, then the project will not compile. re-starting vs solves this.

I would initially assume that your issue is similar IF your dll-files
are not in the GAC or in the project directories -- is this the case?
