Linux 2.0.81 Update
An updated version of Cava Packager 2.0.81 for Linux has been released containing a workaround for a wxWidgets issue.
wxWidgets has some problems with recent gtk releases ( for example gtk2-2.24.10-3 as released with Fedora 17 ). In particular wxFileDialog::GetDirectory it seems always returns the default path rather than the selected path. This release of Cava Packager works around this by calling wxFileDialog::GetPath instead.
wxDirDialog::GetPath also suffers some problems. In the directory selector dialog, if the required directory is 'Opened' in the dialog, with no inner directory selected, the default directory is returned. This can be worked around in usage by returning up one level in the dialog and selecting the required directory.
