Why is the cursor moving around in Perio?
Perio 2 has a Quick Toggle feature that allows you to jump to a value with ease. If you are unintentionally invoking this feature, it may appear as though the cursor is unexpectedly moving back to the original position. Double-click on a value to stay there, rather than single-click, which will move the cursor back to the original location. You may also disable the Quick Toggle feature entirely, if you do not wish to use it.
See our Perio documentation for more information about the redesigned Ability.
