I’m literally going mad still having no clue on how to re-gain the darn keyboard input on WindowsXP with my wxwidget wrapper, after loosing it for switching to another window. The very same code works on ubuntu linux like a charm and this is true for p3d 1.5.4 and 1.6.0 - why?
Shouldn’t be enough this code
wp=WindowProperties()
wp.setForeground(True)
base.win.requestProperties(wp)to have the keyboard back???
Here some working code to try it out - launch it from a console - type some keys after the launch and you have it - swithc to another window or click somewhere outside the window and then come back and type keys - you have it no more. Why why why?

But of course I can’t say it really got that meaning so it’s just pure silliness sometime come to me so never mind…
