I've been checking on the eValid documentation, but I didn't see any answers to this …
Why doesn't eValid record mouse wheel actions?
Do you think that is unimportant for eValid?
The answer to this is, they are not needed if you are testing a web application StephenD.
If you need to reposition the browser screen, all you need to do is send a click event to a DOM element that will be on the screen after the browser responds to it.
During recording, if you scroll down (using the slider or using the mouse wheel) any actions you take "below" the landing page view are recorded at their correct DOM indexes and are played back into the browser in the correct location.
For the record, the eValid command you may want to use is:
ElementClick wid idx [x y]...
This specifies a window by its window-ID, an index in the page, and the offset in pixels.
