Thanks for using ZimaOS.
Do you have another PC or Mac? So that you can test it in a new environment.
Would you please try it in a new browser?
Also, when entering the ZVM, do you move your mouse cursor into the UI(and click on it) so that the ZVM can capture your input from your keyboard and mouse?
Do you use English and do not use any of the non-English input method?
Take a screen record of your operation process so that we can better investigate.
Look forward to your feedback.
