Words in HTML Popup auto moves to next line with a space

Hi,

I tried converting a layer to kmz and open in Google Earth. However, the width of the HTML popup appears very compressed. On closer inspection, I realised that a space in the entry caused the phrase to move to the next line.

However, when I verify the HTML Popup in ArcMap Layer Properties, the appearance looks fine. Does anybody know how to resolve this?

I am using ArcGIS 9.3.1.

Thank you.
