Open files within one instance of Excel

[Guest]

Hi,
I want to open (by doubleclick in explorer) files within one instance of
excel (to use CTRL+Tab to change from one file to another).
Can anybody help me? Some days ago it was working, but now ...
I have Excel 2003.

Hello kopa999,

Try Tools + Options + View Tab. Uncheck "Windows in Taskbar"
