Mr. Humphrey, I have spent a little time looking at the problem with Create_GEO and Destroy_GEO and reproduced the bug you reported. The bug has been fixed and the fix will be available in 5.0.8. Create_GEO and Destroy_GEO can now be called multiple times in pairs: Create_GEO ... Destroy_GEO ... Create_GEO ... Destroy_GEO We also support multiple calls to Create_GEO as long as the same number of Destroy_GEO's are called: Create_GEO ... Create_GEO ... Destroy_GEO ... Destroy_GEO Note that the when you call Create_GEO twice in a row, the same handle will be returned and that handle will only be truly destroy on the final call to Destroy_GEO. I hope this simplifies your programming in the future.
