Hello,
When using ChartWithLogging on Windows 10, the buttons (and everything else) appear correctly with a light grey background. If I run the EXE in Windows 7, the buttons have a transparent background so they are the same colour as the MainForm background.
I also tried Visual Studio right in Windows 7 and even in the design window, the buttons show up with a transparent background. I have no idea where to change this. A basic button shows up with the correct background colour.
2 screenshots attached: Win7, and Win10
Thanks
