I use the Worksheet_Change(ByVal Target AS Excel.Range) event to update input values (I replace "-" character with 0) on Office 97 (NT4)
For most of the computers, the Target.Value is equal to the value

But on some computer the new value is not available. Indeed, the Target.Value is still equal to previous value of the cell

Example
So when I have a cell equal to
The user inputs 1
The event replaces the - with 0 instead of keeping 1

What's the problem? Thanks for email me your response to

Many thanks for your help
