I think propably everybody faced at least once the fact that when
you copy multiple text selections within Office 2003 (and earlier) a
dialog box with the Cilpboard data displayed appears.This can be
quite anoying.To disable this dialog box navigate to :

- HKEY_CURRENT_USER\Software\Microsoft\Office
\VERSION\Common\General\

Note:VERSION = 9.0 (Office 2000) , 10.0 (Office XP) , 11.0 Office 2003


Create or modify here in the right pane the entry :

AcbControl

(create: right click , new , REG_DWORD [DWord Value] and name it as above)


Doubleclick this entry and set it's value to: 1 (disable dialog) or 0 to
enable it again.


Close registry and restart Office !
