I've had a situation where I am using Excel 2003 on my desktop and need to transfer my large workbook to a laptop using 2007. I had some issues early on but subsequently learned the convert function and that seems to have solved the issue. However, my desktop hard drive has crashed and I'm going to buy a new desktop and it has 2010 loaded.

Are there any issues going back and forth between 2007 and 2010 that would cause compatibility problems?

Thanks for any info you could give me.
