That said, here is my take...
AFAIK scrolling wheel support must be built into the application, and
I do not see PST doing that for E-Prime. Then again, maybe you could
do this by calling the appropriate Windows API, but that is not a job
for beginners.
For continuous collection of mouse data, please see the MouseDevice
topic in the online E-Basic Help, and look through the example
programs that you may download from the PST web site. I do not think
they have one that does exactly what you want, but they do have
programs that will show all the necessary techniques that you may
then put together. I have actually seen a demo of exactly what you
want, so I know that EP can handle this well.

As for continuous data collection, I was sort of wondering what exactly is meant by this. For one, not many people seem to know that EPrime can collect on- and off-presses (press / release, key-down / key-up, in other programming languages) independently, so you could have something like
Slide1 shown until key-down (default)
...do stuff here...
Slide2 shown once key-up (look up {key} nomenclature in e-basic help)
Or, if you like:
Slide1: infinite duration until {SPACE} key-down
Label1
Slide2: 1 ms duration (no sync)
If Slide2.RESP <> {-SPACE} goto Label1
Depends all on what you mean exactly by 'continuous collection'. One thing I've learnt is that you will feel very sorry for yourself if you decide to do something like this:
for I = 1 to 1000
c.SetAttrib "CursorX" & cstr(i), Cursor.X 'this is not exactly eBasic, but you get the point
sleep 1
next I

For the record, the mouse most certainly does allow {-} releases, as
long as you set its CollectionMode to recognize releases and use the
proper {key} nomenclature. Please look again at the appropriate topics
in the online E-Basic Help.
That said, unlike any other device in E-Prime, you can access the mouse
directly without any input mask, so you could do continuous data
collecting without regard to any of that. Just takes a bit of thought
and coding.
