Why doesn't SourceSafe respect the "Open this database next time..." option?

Question

Using Visual SourceSafe's "Open SourceSafe Database..." command, there is an option at the bottom of the dialog to "Open this database next time I run Visual SourceSafe."

Typically, when checking this box the most recent opened VSS DB is opened immediately upon launching VSS (even if it's a second instance of VSS running).

I'm seeing this option not respected. All launches of VSS result in the same DB being opened at launch.

Removing all the registry entries under HKLM\Software\Microsoft\SourceSafe\Databases and HKCU\Software\Microsoft\SourceSafe\Databases doesn't help.

Additionally, the HKCU\Software\Microsoft\Sourcesafe\Current Database value was accurately pointing to the DB I wanted to be opened, but not the DB that was VSS was actually opening. Same with the similar value under HKLM.

Answer 1

An environment variable had been set to force that particular database.

When SSDIR is set, the VSS dialog option is ignored.

Clearing the SSDIR variable fixed the issue.
