Context menu: Open, Properties, Delete options shouldn't appear when clicking on blank space

Together with @JKolodziejczyk and @apospieszny, we have been testing NanaZip as the final project for the Software Testing course at Jagiellonian University. Here is one of our results:

When right-clicking in NanaZip's explorer's blank space the context menu is shown. There appear options such as Open, Properties, and Delete, which don't do anything after clicking, so therefore they shouldn't be available.

Used version: NanaZip 1.0 x64
