This Bugzilla instance is a read-only archive of historic NetBeans bug reports. To report a bug in NetBeans please follow the project's instructions for reporting issues.
When attempting to mount an archive which is already mounted, but hidden, the open archive window just fails to highligh the archive. There is an explaination of why the archive cannot be openned. As it would not be obvious to most users how to find which hidden archives are mounted, a better option would be to ask the user. "This archive is already mounted, do you want to make it visible" i.e. un hide it.
Obsolete milestone, please reevaluate
