A year ago, our plant director was transferred to our plant (in the US) from a plant in Brazil. He brought his Brazil issued laptop with him and used it for about 2 months before being requested to return it (it was coming off-lease). A new laptop, a Dell Ultrabook, was purchased with Windows 7 64-bit installed, Office 2010 was installed locally. Everything was setup using US settings. The plant director copied files from his old laptop to his new laptop, Windows Easy Transfer was not used. Problems started right away. When he receives PowerPoint presentations from other people in the company with embedded Excel graphs, the number formats change from 0 decimal points to 5. The decimal points are changed to commas. The most recent problem was with a PowerPoint presentation he created. On his PC all the numbers look normal (in the US format). When he sends his presentation to others, the currency changes to Brazilian Reals. We have looked at all the settings we can find and they are all set to US format. We've looked at many many websites for help and so far are without a solution. It seems like it has to be something he copied over from his original system, but we can't figure it out. He's at his wits end with this and wants me to order him a new PC, but I'm afraid when he copies his files again, the same problem will reoccur. Has anyone seen this issue before? What are we overlooking?
