/*
Reasons NOT to use wxDirPickerCtrl, but wxButton instead:
	- Crash on GTK 2: http://favapps.wordpress.com/2012/06/11/freefilesync-crash-in-linux-when-syncing-solved/
	- still uses outdated ::SHBrowseForFolder() (even on Windows 7)
	- selection dialog remembers size, but NOT position => if user enlarges window, the next time he opens the dialog it may leap out of visible screen
	- hard-codes "Browse" button label
