We should not be using v5 for explorer.exe, right?

This hack confirms that ComboBoxEx with short height also shows fewer elements on windows: [0001-t.patch](/uploads/1d5a509d82bb9fd71c3e59db9b5c190c/0001-t.patch)

So we need to fix explorer, either removing that flag or setting a height like I proposed.
