That is a good possibility. The dialog form probably has a minimum height policy set… which is fine for most display settings. For smaller resolution screen settings when viewed at 125% or 150% it could be an issue.
I’ll check the form and see what I can do. There’s definitely an art & science to get ui forms to look good, while being able to adjust. And sometimes you have to decide for example - is it worth it to make it adapt to outdated resolutions like 640x400?
Would if the OK button is highlighted. I forget if the ok cancel buttons use the alt selection… like alt-O to highlight Ok, after which you could press enter. There would be an underscore under the Ok in the ok button… but of course in this case we cant see the button. The other option is to use the Tab key, which will cycle to the next widget… eventually you’d reach the Ok button, but right after that is Cancel.
