Tileindex of DGN's being opened as shapefile layer

[Bart van den Eijnden (OSGIS)]

Hi Jacob,

I can only state that I have seen this problem as well myself with 
Mapinfo TAB files in a tileindex, I was also using them through 
PHP/Mapscript. In the end I used Mapinfo seamless layers to get around 
that, but that won't be an option for your DGN's.

Best regards,
Bart
