Here's what I mean: http://161.53.64.5/~perplexr/mirc.jpg

There is no slider to drag to see the partly hidden window. Moving the window itself would mean displacing it (if it was a channel window). I had sliders appear in such cases in older mIRC versions but this new one doesn't show them anymore so I can't access windows that get hidden beyond borders (if I change the screen resolution for example).
