First impressions

Just downloaded a trial of Captivate 12.3.0.12.

1) Upon installing (Windows 10), it launched... Internet Explorer?

How and why? Why would Adobe hardcode that in instead of simply obeying my configured default web browser setting in the OS like a well-behaved app?

2) The initial window that appeared alongside the blast-from-the-past IE was too big to fit in my laptop display and *could not be resized*. That made navigating the window nigh impossible.

Once I created a new project the rogue unresizable window was replaced with the project window, which can be resized. But still. Adobe: we live in a diverse world of many screen resolutions, and other apps seem to work with that. Why doesn't Captivate?
