I have created a small application at work, which calculates costs based on invoices (nothing fancy). As with a lot of my Windows programming, it is written in c#.
Because I sometimes need to change the (hard coded) formulae, I have put the executable on the server, and each client has a shortcut, which was fine.
Then, I 'updated' to IE7

Does anyone know how to solve this? (remarks about uninstalling IE or using proper languages ignored

Thanks in advance,
Adam
