Ctrl key in pwn box doesnt work for me. Anyone else?

Hi was wondering if anyone else experinces this issue when using pwn box it does not register my ctrl key presses so I cant kill a process running in a teminal window on the pwn box.

ANy one know how to kill a process while a teminal is running in pwn box without the use of the ctrl key?

the Ctrl button is entirely broken in Firefox for Pwnbox. I have cancelled my vip+ due to this. It is not possible to rebind it nor use a virtual keyboard either. Changing layout is the same. Firefox in safemode with factory defaults and no plugins is also broken. Clearly this has been going on for 2 years. I did make a support ticket for this, and the support person said “Use chrome”. No thanks.

Ya pwn box is a nice idea but it far inferior to just using your own vm. Pwnbox is way too slow and laggy unless you have a very good quality fast internet connection and even then its still kinda slow
