The Automatic return to Left-Click (Single Right-Click Only option) uses System Level hooks. Any conflict with other software may require disabling this option from the TouchRight Menu.
In 95/98/Me/NT, there can be a conflict with IMG's My-T-Pen, My-T-Touch, My-T-Soft, OnScreen if the "Track Pointing Device at all times" is OFF, and the Automatic return to Left-Click (Single Right-Click Only option) in TouchRight is ON. Either turn this option off in the TouchRight Utilities, or set the "Track pointing device..." ON in Configuration | Operation Options.
