Thanks, that is the sort of thing I am looking for and will give it a try -
hoping it doesn't block Lotus and DBF conversions.

It would be nice to disable the compatibility pack but I haven't found a way

You might try creating this dword reg key

HKEY_CURRENT_USER\Software\Microsoft\Office\11.0\E xcel\Security\FileOpenBlock\Converters

setting its value to 1. XLSX files are blocked for me in Excel 2003 after
this. Might be other things too but you can always change the value to 0 or
delete the entry.

| it!). Because of compatibility and bug issues, I often have XL2003 and
XL2007
| open at the same time and I find that whichever version last had focus is
the
| one that opens the next file I 2x-click on. Trouble is that I can
| inadvertently open an XL2007 (.xlsx) file in XL2003 and not even notice
the
| conversion has taken place before I re-save it and risk losing some of the
| data. I suspect it is the process of opening the files in XL2003 and then
in
| XL2007 and vice-versa that leads to the data-loss. What I need is to
disable
| the file conversion process that takes place when I open an XL2007 file in
| XL2003.

| If your problem is that double-clicked XLSs open in Excel 2007 rather

|

on
