Aaltoverb scroll goes flooey on some dual-screen setups

[randyjonesworld]

While running Aalto verb on a MacBookPro M1 (MacOS 12.6.2 Monterey), hosted by Reaper DAW in dual screen mode, when I try to scroll presets on the secondary screen the cursor goes “flooey”. It moves off the preset panel and marches steadily downward.

This may be the same problem I wrote to you in the second e-mail the other day, following the sumu dual screen crash report. I thought perhaps these are related, since both are dual screen UI misbehaviors. But as I see that same mouse behavior in Aaltoverb, but unlike Sumu it does not crash when spawning its UI on the Apple Cinema screen, they probably are not.

For the record, I see this same problem on all Aaltoverb dials, not just the preset scroller. And on the main controls it is preventing any changes at all from being made. The mouse runs off to the main screen (up not down for me) before the dial even has a chance to move.
