I have a form that worked well until I used it on a separate machine with higher resolution than the machine I used to develop it.
1. The form paints as expected and fits the screen size perfectly.
2. Any action (such as a button to set a filter) causes the app to resize to roughly 1/4 the original size.
Up until this point I did not have issues with this. I [thought] that 2019 came some way forward with the resizing issues but I'm sure I missed a key point of it along the way. I read up on perform auto size but I have not been able to place that code anywhere that has made a difference.
