Hi,
Still the error with the form icon on the taskbar in the new build.
The icon is not showing good.
Hi Mark, are you using a custom theme or copied the theme file into the project? The change was a setting in the theme.
See this: http://demo.wisej.com/apps/userdesktop
It uses this image: 
It scales well in the taskbar.
I noticed a different problem with the icon in the title of the window with some themes due to scaling.
Let me know if the same sample is what you need to do.
Best,
Luca
