If it weren't Excel 2007 I say just re-register Excel, but I'm not sure that
works with the newest version (that=running with the /regserver command line
parameter).

I'd guess if you went to this key with RegEdit:

HKEY_CLASSES_ROOT\Excel.Sheet.8\shell\Open\command (or 12 if you're
referring to XLSX files)

you'll find a %1 at the end of the Default value. Edit that out if so. If
you see it at the end of the "command" value do that too.

| hi all -
| thanks in advance for any help on this.
| i have about 10 computers in our office. all just upgraded to office2007.
| it seems now more then half of them have a strange issue.
| whenever a user opens an excel file it opens but it opens twice . for some
| larger spreadsheets this comsumes system resources and bogs down the
system .
| once both fully open you can close one but can't seem to find why it opens

| any ideas?
| thanks again
