I have a following situation:
I work on 3 computers and on all of it I have Exel 2007. I create workbooks and save them. But on first computer a workbook is saved with extension *.xls, on second - *.xlsm, and on third - *.xlsx. Why does it so? What and where I have to set up for saving my workbooks with one extension?
Some more details:
On one computer I have SAP GUI 718.104.22.16869. On another computers I have SAP GUI 722.214.171.12477.
If I open a workbook on computer with SAP GUI 7126.96.36.19969 the workbook's extension is .xls.
If I open a workbook on computer with SAP GUI 7188.8.131.5277 the system automatically change extension to .xlsm and I can't open this workbook on first computer and can't execute this workbook on computers with Exel 2003.
Why does it so? How can I influence on it?
