On a couple of laptops with screen resolutions of 1366x768, I have found that the Batch Converter dialogs aren't properly displayed. The Confirm or OK button (I can't remember what it's labelled as) will not display - only the very top of it. This is the case no matter what size the batch converter window is. In fact upsizing the window makes the file list expand, but does nothing to show the contents below it properly. Screenshot attached.
