Cannot input Japanese after upgrade to Catalina
I have resisted upgrading to Catalina because it breaks a number of programs that I use frequently. I found replacements for these and decided to upgrade from Mohave. Everything seems to work fine except for the fact that I cannot input Japanese at all and with Chinese, I can only input the first character on a line. I have the proper languages and inputs set in System Preferences; I tried booting in Safe Mode; I tried deleting the inputs and reselecting them. All to no avail. Any ideas about how to fix this?
