I have some strange behaviour happening when importing a MapInfo .TAB file into QGIS. One feature contains internal rings which are ok on initial import but do not show on the first .SHP save. I can see the ring perimeter but selecting picks the feature as a whole, shading in the ring areas. It's only if I save again that they appear properly cutout and all appears ok.
I've used the MapInfo file with Manifold and no issues in that software. However saving the file as a .MIF in Manifold and importing into QGIS I lose the rings in the initial import and again need to save twice to .SHP to get them to appear ok.
Just wondered if anyone had an explanation?
