Acer Aspire Touchpad Zoom

[Baboonboy]

Does anyone know how to stop webpages from zooming up when I brush the touchpad on my Acer Aspire laptop? It's very frustrating. Most of the answers online are quite dated and the facility to disable this function doesn't seem to exist, however, it's obviously been a problem in the past. I can disable the touchpad completely but this isn't very useful when browsing. Many thanks. BB
