Hi @Anonymous. I don't know what fixes have been tried before, but there are a couple things to look into. There is an external XML file, usually named "iLogicBrowserUiFormSpecification.xml", that I believe is usually stored within the DesignData\iLogic\UI folder, where all those global iLogic form specifications are being stored. If the user has recently moved the location of their DesignData folder to a new location, such as on a network drive (Application Options, File tab), and they did not copy that folder path and file to that new location, it may not be able to find that file. Also, there is a new functionality that I just noticed about a month ago, where you can right-click somewhere in the open area of the Global Forms tab (below the tab), then choose 'Refresh' from the right-click menu, that seems to correct some external forms related issues. I skipped from 2022 to 2024, so I do not know if that was available in the 2023 version or not.

Edit: Looks like I took to long typing. 🙂
