Compatibility/Windows 11

[Pamela Green-Nanni]

I recently got a new computer and it has Windows 11.  I've downloaded Open 
Office and Java, but I've lost a lot of functionality.
1.  I cannot find the "T" where I can type into the presentation.2.  I cannot 
get  "Format Line" to work.3.  I cannot get "format Area: to work.4.  I cannot 
make borders or any colors to work.
Please advise with simple instructions on what I might need to further download 
in order to get these to work.
Thank you,
Pam Nanni
