We're working on migrating up from 2019R2, and noticed that our windows with horizontal tabs in them can't be switched between (the tabs appear, but none get highlighted and appear as active, and we can't switch to other tabs). Going through the versions, I see that it works in 2022, but not in 2022R2 or in 2022R3.
I see in the 2022R2 Known Issues "If the application calls Windows APIs to hide MDI sheets or set certain MDI sheet as background, avoid enabling the TabbedView option on the sheets at the same time. Otherwise, the sheets may not display as expected.", but I honestly need clarification on what this means. We definitely hide sheets, but to my knowledge, we use the native PB methods to do so. Not sure if this is related or not.
What should I be specifically looking for in my code? The wording on "calls Windows APIs" gives the impression that it doesn't simply mean calling hide() or setting the visible property to false on the sheet.
I feel like we're not on the same page. It seems like there's a bug with the tab pages your application is using, which is unrelated to the content described in the document. The document describes a limitation in using the TabbedView feature, which is not related to the tab pages.
Therefore, please report this issue to our ticket system: https://www.appeon.com/standardsupport/newbug so that it can be properly received and tracked.
Please also provide a sample PB test case (with PBT / PBL) when you submit it to the ticket system.
