Using 10.1 Berlin Update 2
I have a simple FMX app that contains 1 combo, 1 editbox, 1 button and a grid. Everything works on most win 7 and all win 10 pc's I've tried. But, the combobox (with 3 items in its list) does not display its dropdown list on this Win 7 pro SP1 pc. On most pc's the dropdown list is displayed by clicking on the arrows at the right of the combo. I can scroll through the list by using the up and down arrow on the keyboard, so I know there are items in the list.
I have checked the video settings on the pc and they have directx 13. What could be causing this issue?
Thank you.
