Hi Stan,
After working successfully with many large segment worksheets ( >3000 lines) in Excel it will occasionally blip when creating the csv file for input into the Multiple Segments Combination filter. A cursory look at the csv file will probably not reveal the error. However, on import into the Multiple Segments Filter and clicking on Count Passing Tickets you will get an error pop-up as shown in the attached Pic_1. This pop-up extends across my dual monitors and beyond. EL is now locked-up. The only recourse is to Ctrl-alt-delete EL. No need to reboot. Recreate the csv file, re-start EL and everything works fine.
Of course the error in creating the csv file is not a fault of EL. However, I thought you would be interested to know what happens when trying to import a corrupt csv file which results in a parsing error. Perhaps, a little of your programming wizardry could prevent the whole program from locking up. Please check the attached Pic.
