--- Comment #5 from Mark K markk@clara.co.uk 2012-12-08 14:31:18 CST --- In case it might be relevant, quote from the WinUAE 2.5.0 changelog, the first version with resizeable GUI:
* This is a hack, rebuilds classic Windows dialog resources on the fly while adjusting GUI element coordinates and size. * GUI size after resizing may not be exactly what you expected. * Windows always closes and reopens after resize. It is also normal, can be improved, later if ever..
