I will give those things a try when I get a chance. I want to ask you do you think that reinstalling might help. You know "he installs last, installs best"?
If so, then I just backup my configuration? Uninstall/Install. Restore the configuration. Will it take my certificate again?
Please do the other tests to see if WindowManager or Ultramon are involved.
Re uninstalling, doing a config backup, then uninstalling Opus is certainly worth a try. Try before restoring the config backup, in case the issue is triggered by configuration changes, scripts, etc. that have been installed. Be sure to reboot when prompted, to make sure all components are properly removed/replaced. Your existing certificate should work. Use Settings > Backup & Restore to make the config backup.
I may uninstall/reinstall. We are reaching the point where I am fine with my work around. Computers are like that. Highly complex. It is hard to get everything perfect.
