Textarea.backcolor on windows

Hello, Does anyone knows how to solve Textarea.backcolor when it does not change on win7
I need a simple kind of Alert: text change to red and background to white then the opposite, i have my code in a timer action:
if Alert1.BackColor=&cFF0000 then
end if

I don’t have access to Win 7 at the moment, but Have you tried Alert1.Invalidate after setting the color ?

It should force a redraw of the control, and hopefully update the color.

I had the same issue recently but i am unable to reproduce it in a simple app for a Feedback report :frowning:
