BackColor of Sheets not working

Hello,
it seems backColor in sheetwindows does not work: in the IDE I set to black the backColor of a sheetwindow, but when the windows shows, the backcolor is more or less the backcolor of the parent window.
I could fix the problem using the sheetwindows’ paint event:
g.forecolor = color.black
g.fillRect 0,0,g.width,g,height

Is it the expected behavior in Mojave Xojo 18r4?

Thanks

Hi Carlo - there is a private bug report on this and it is marked as fixed, so I expect that it will be sorted in a coming Xojo update.

Good to know. Everybody is happy no leave aside workarounds and get things fixed.
Thank you.
