@KevinH.
I think I know what the issue is.
If the cursor is in the cbFind field then pressing "Find" takes the focus to Code View and that is understandable.
The problem arises when we are in the cbReplace field and then press "Find" (because we can). Then the focus stays in the cbReplace field.
If you remember
this commit then maybe you just need to add some code there for the cbReplace field to make it work well.
