I am using Office Pro 2003 on a Win7-64 machine. I have two Microsoft mice - a modern and an old, let us say - and on both of them the wheel-click is set as double-click. All programs in my machine recognizes the double-click on either mouse except for Office 2003: for a double-click I still have to double-click the wheel or the left button. Everything works fine but for this idiosyncrasy. I wonder if anyone has experienced it elsewhere? Thanks in advance for all opinions.
