Delphi10.4.2, Theme, closing Modal dialog

[richardcarn1 0]

Using Delphi 10.4.2 Pro with a Theme enabled, when I close a Modal dialog form, upon returning to the app main form, the main form closes. Non-modal dialogs are OK. Under the IDE, the app shows that it's running still. Outside the IDE, Task Manager shows the app closing. All was good under 10.4.1. Are there any new requirements for Themes in 10.4.2? Thank you.

Can you reproduce in a simple app? If yes, can you attach it here?

Thank you. I will work on a sample project.
