Effectively Ronnie Po, the themes files were the culprit here. Once I installed the latest from our inhouse developer working on them all came back to normal. Thank you all for your many suggestions.

Are you using UI Themes? If so, check the "window" section in your theme.json file and make sure that the files referenced in "min-button", "max-button" and "close-button" are available to the app at runtime.

Hi Michael,

What PB version? What's your environment? What runtime versions are present in your system?

Regards,
Francisco

PowerBuilder 2022 R2 build 2819 and runtime is 22.1.0.2819. The Windows edition is Windows 10 Pro OS build 19045.3448. My workstation is the HP EliteBook 655 G9 Notebook PC.

Hi, Michel -

Are you expecting the upper-right corner of the PB IDE to appear similar to this?

Does it instead look like this?

If so, click the "Restore Down" button indicated by the red arrow.

Best regards, John

In the attachment I have a response window and on the top right of the response window the close button is expected instead we have a white area. Also, notice the two dddw with the properties defined as having Always Show Arrow and they are not displayed at runtime. However if you click in the white area where the close button is or on the dropdown then the click fires as expected for either of them. This is not only happening for the response that I have attached but throughout the application.

Hi Michel;

    This seems like it might be a simple O/S "low on resources" (especially GDI resources). Did you try a simple complete reboot (shutdown + restart)?
