It seems that the latest(?) update to the website builder added a feature that causes the site to scroll itself to allow the viewing of an entire RE's text box when scrolling over an RE in the Mystic Enchants section of the builder. Or some such.
This has lead to a few issues that I've noticed on my end, no idea if it's affecting other people, and its annoying. Those are:
When you scroll over a RE and the site tries to adjust for the text box it results in your mouse being moved off of the RE as the screen realigns itself. Note I have a large monitor and the text box will still end up off the screen sometimes after realignment as the text box is tied to your mouse location.
The site will create a second scroll bar to attempt to move even further beyond the site limits, I assume, and you end end up having to scroll the new bar into the old scroll bar to eliminate the 2nd one.
Anyway, I recommend adding a blank text window area that fills in with all of an RE's text data when moussing over an RE in the Mystic Enchants section of the website Build viewer.
If a RE description is too long for such a thing then, maybe have the check box of each RE dump its text into the side text data window. And giving the window its own scroll bar?
