Powershell - applying 'wrapText' style to some cells causes the whole sheet to wrap text

Question

Can someone tell me why the Powershell code below causes all cells in the worksheet to take on the 'wrapText' style, instead of just the cells specified by range statement?

The cell highlighting is only affecting the specified range, as is the bold font, But WrapText is going everywhere!.

and if I specify something like:

 $ActiveWorksheet.Range("Q1"),Style.WraptText=$false

It turns off WrapText for the whole sheet.

Is there a way to affect just the desired cells?

thanks
