It was unable to locate tracks in the same location? I will look into that, but it shouldn't happen - thanks for the feedback. You are saying that this is a mapped network drive? We are looking into a solution to allow "bulk relocation" of tracks (i.e. RM will search from a new root location and try to match up existing tracks with files on disk). This would make it easier to move workspaces between computers etc.
Yes, IDX files are now created for each file - the location must be writeable. Although I know this might be annoying for some (the files are quite large, as they contain sonar imagery and indexing info), there are also big benefits - e.g. sharing corrected files across workspaces, no need to reimport files to other workspaces once the IDX files have been generated once and, most of all, far better performance when reading sonar data so that we can now do things like show SS mosaic at all zoom levels.
