Any way to disable this graphical glitch?

[Laurent Dufrechou]

Hi,
I'm using a wx.TextCtrl with a black background.
Let say my TextCtrl instance is 't'.
When I do t.Remove(t.GetLastPosition()-10, t.GetLastPosition())
The text is selected THEN it is deleted.
As the selection color is Blue it makes a graphical glitch.

Is there a way to set selection color to background color or perhaps another
way to avoid the glitch??

Thx.
