Can you please share a screen recording? I am not clear on this behavior.
Oftentimes it is easiest to share a screen recording for issues like this to quickly show me exactly what is happening. I use Loom for screen recordings since this is a free and easy to use app.
Two video files attached, both screen grabs from my MacBook Air M2. The cursor behavior is the same on my Mac Mini Intel. Both machines on Monterey with all updates, running VAI 3.3.0.
The “Correct…” video shows the Save dialog box opening up and cursor placement in the filename text line. I then used arrow right to move the cursor to the right in the text box, which action you’ll see.
The “VAI…” video shows the “Export As” dialog box opening, and cursor placement in the filename text line. When I use the arrow right key, the cursor does not move, but you can see the image frames advance behind the dialog box.
