Same what happend with the grid (huge fonts, now fixed, see thread https://www.tmssoftware.com/site/forum/forum_posts.asp?TID=13121&title=tmsadvstringgrid-font-bad-in-latest-version-for-me) also happen with the TAdvDualListBox.

It only turns to normal, when DPI awareness is set to none or unaware in the Project Options.

Picture where is displays way too huge fonts (Font set to Arial 9, Normal):

What Delphi version do you use?

What exact DPI awareness option do you use?

I use Delphi 10.3.1

Per Monitor V2

We traced & solved this issue. The next update will address this.

Thanks, but the next update will take too long. Is there again an incremental update available?

You can request is by email.
