This is just a recent problem I have been experiencing. I am receiving a couple of errors that I am not familiar with. Let me explain the method: Open a point table Create Thematic map > using the grid option. Accept defaults. The grid displays, but should I zoom out or in an error message pops up Raster Engine error: 0. I try to create another thematic grid but an error message says "error creating grid file. Error creating grid file during interpolation process." I have to completely shut down before I create another grid file. I am only allowed to create one then the error messages start appearing. I am running MI5.5 Any suggestions or thoughts.
