I was going to close MarkPad on Surface Pro 4 and hit this. Latest release build from ClickOnce install.

Guess it's related to a extremely big screenshot I paste and save in the md... shot

This might be fixed in MahApps.Metro but when I last looked at this the interface has changed and ResizeWithGrip has been obsoleted - might be a minor thing, but needs investigating...

e.g. https://github.com/Code52/DownmarkerWPF/blob/200df7b3d571dd5a7e4820246c5d4f2d3761021b/src/MarkPad/Document/Controls/HyperlinkEditorView.xaml#L14
