One issue is the handling of .ecw files. In the past we have used
the MapImagery Plugin To get .ecw files into Mapinfo - this worked
fine. With the new version of Mapinfo it offers .ecw support.

I noticed that since version 5.5 of MapInfo it is possible to display
a special file format called MapInfo Grid, very useful to display
elevation or other interpolated data. The only way to query the grid
is the Info Tool.
Is this feature (grid querying) accessible via MapBasic? Also, is
