Tool wanted

Because I have recurring problems with bgl files, I'm looking for a way to determine which files FS tries to load for a specific coordinate.What I search is something like LWMViewer, a utility which shows me exactly which bgls are currently loaded or should be loaded and cannot be found for some reason.Such a tool would be my only hope to find out what's wrong at certain places where e.g. I have terrain polygons in the middle of the sea and I don't know whether they're caused ba some missing coastline or scenery file or wrong landclass, nor what the filenames of these are.Does such a tool exist at all? How do others sort out such problems (e.g. double coastlines/rivers caused by different bgls with similar data, missing coastlines because of file not there etc., all that for 3rd party scenery, not the default)?Andreas
