I just need selections of this database which I can then modify in excel. So I opened the attribute table and made a selection based on a specific value for an attribute, and copied that selection (about 30.000 objects) via the clipboard (ctrl-c) to a new Microsoft Excel file, then saved the excel file and repeated the process for another selection. This worked perfect for some time. However, some selections won’t copy: when I press the copy button the programs turn to ‘not responding’ and won’t snap out of it anymore. Selection size when this happens is about the same (about 20k to 35k objects).<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p><p class=MsoNormal><span lang=EN-US>What could be the problem?
