I have tried to reduce my code to a minimum - so I have removed all my 
database access stuff, display fields etc - what I was trying to do was 
experiment with absolute positioning of buttons etc - I have retested the 
code below and the abbreviated code below still blinks. So, here it is :-

Shoes.app(:title => "Membership Types", :width => 400, :height => 160, 
:resizable => false) do
  @a = button "|<"  do
  end
  @b = button "<"  do
  end
  @c = button ">"  do
  end
  @d = button ">|"  do
  end
  animate do
     @a.displace(40,0)
     @b.displace(60,0)
     @c.displace(80,0)
     @d.displace(100,0)
  end
end

Possible (probably) I am going about this the wrong way!

Hi Roger,

You turned off Aero, but still flickering?
Umm...

Could you show us the code? I'll try to confirm on Vista pc.

Hi Roger,

Thank you for sharing your code.
I confirmed the problem on Vista.
I don't have any solution for Vista flickering problem so far. :(
But I'd like to show you another way.
I'm not sure this code suits your taste, though.
Anyway, it's not flickering on Vista. :-P

Shoes.app do
  style Link, underline: nil
  style LinkHover, underline: nil, stroke: red, weight: 'bold'
  @a = para link("|<"){alert 1}
  @b = para link("<"){}
  @c = para link(">"){}
  @d = para link(">|"){}

  animate do
    @a.displace(40,0)
    @b.displace(60,0)
    @c.displace(80,0)
    @d.displace(100,0)
  end
end

Tried it out - definitely a useful workaround pending resolution of the 
vista problem.
Thanks
Roger

Thanks for the suggested code - I'll dig deeper into it and give it a try!

Hey Roger-

This is actually a known issue on Vista, actually. It's going to be fixed
soon; hopefully by this Saturday, actually. One of my friends is working on
it. We fixed it for Windows 7, but there's still a bug in Vista. It's
actually not technically a bug in Shoes, it's a bug in Vista, but there's a
workaround.

-Steve

That's great - thanks!
