Hello, I wanted to transfer my automated systems on a new computer running on windows 7 but I can't get my spreadsheets working correctly. I use the same excel 2006 version and the same spreadsheets but there is something in the format that makes it unreliable. It's weird because the errors are not "stable"... For example, when an order is filled, the macro reads the "filled" status fine 10 times and then the 11th time it doesn't work. I am quite sure of it. I have tried to format cells, to change excel options, to change system number separators, regional properties... I can't find where the problem is. Does somebody has an idea of what it might be or can point me a way to configure excel the exact same way as it was working on XP? Thanks a lot.
