This is pretty minor. I can work on a fix if no other devs want to worry about it (if it is actually a bug)

This is in the code:

# XXX, no redraws
# text = bpy.path.display_name(context.window_manager.keyconfigs.active.name)
# if not text:
#     text = "Blender (default)"

So whoever add this was aware of the problem, the issue is that the UI code can't currently redraw a popup like this, it will use the same button layout until you close it. That would be nice to support but it's fairly complex to do and goes deep into the UI code.

sounds good. We can just leave it as is for now.

hi there :)

That is the welcome screen..

I think, this issue is disconcerting and confusing for new users, especially for them, who come from programs like 3DS Max and Maya:

The first thing, that they see in Blender, is something which is important for them, seems not to be working.

How can such an issue stay for more than 2 years and everybody seems to be fine with it ?
