Warning with 000.exe and other malware

1 week ago while browsing the web I ended up finding this wonderful software called "Sandboxie".

I installed it on my computer and started testing with different viruses. It simply magnifies the way you can control programs executed within the sandbox. Yesterday I was testing a virus called "000.exe" inside a sandbox, sandboxie does an excellent job containing 000.exe and does not cause problems on my real pc, but my screen looks like this:

 
 
 
So it does not let me access the Sandboxie Control to be able to finish the programs inside the sandbox.
000.exe apparently blocks all keyboard shortcuts and doesn't let them use them.
 
So, is there any way to fix this? Because I think it is something very important, since certain malware like ransomware do something similar.
