In the notes list (middle pane), I enter a search term, which filters the displayed notes. I click one of the notes and start editing it. I switch to an app, and then switch back to Evernote. But when I start typing, the insertion pointer either disappears, or moves to the top of note. For example, if I press the down arrow, I expect the blinking cursor to move down one line so I can edit the next line. Instead, the blinking cursor disappears, and the entire note scrolls down as if the note hasn't been clicked in. If I switch apps again and return to Evernote, now the blinking cursor is at the top of the note, instead of where I left it.
This seems to only happen when I have a search term entered in the middle pane and when modified notes are synced. Once I remove the search term from the middle pane, then the insertion pointer mostly stays where I left it.
The instability of the insertion pointer is very annoying and is driving me to other note taking tools. I have similar insertion pointer problems on Evernote for iOS.
