I've had this happen a number of times, but I don't have a clear repro...
From Slick, I will copy a line, or maybe several lines, then try to Paste into an Outlook email.
In Outlook, I do Ctrl+V ... nothing happens.
I hit Ctrl+V again, and now it pastes.
I do not need to repeat the copy in Slick -- just retry the paste in Outlook.
I do have HTML clipboard format enabled.
This is new with V22, I never saw this in V21.
