I have reverse-engineered my solution to Visio. The *.vsd file is under source control as a Solution Item. When I check out the file exclusively and open it, VS.NET throws an error, "The Handle is Invalid". I can hit "OK" on the dialogue and continue working normally. I googled this error and it seems to happen alot in VS.NET when performing widely varied tasks. However, no solutions seem to be present. Has anyone ancountered this annoying error? Know how to fix it? I have VS.NET, the VSS client, or Visio reinstalled, but I do not trust the IT guys with my machine.
