We have recently upgraded our sotware to .NET 8.0 and I get the following error when trying to open the report editor or the report previewer.

Unable to find an entry point named 'SetWindowTheme' in DLL 'user32'

This was happening on version 2020.2.0 so I upgraded to Demo version 2026.1.4 and the problem still persists.

I want to be sure that it is fixed in the release version before I pay to upgrade the library.

Rich Text Editor. To edit a paragraph's style, hit tab to get to the paragraph menu. From there you will be able to pick one style. Nothing defaults to paragraph. An inline formatting menu will show up when you select text. Hit tab to get into that menu. Some elements, such as rich link embeds, images, loading indicators, and error messages may get inserted into the editor. You may navigate to these using the arrow keys inside of the editor and delete them with the delete or backspace key.
