Balsamiq just have almost ruined my demo to client (
The bug I’ve faced was unaple to position an image within the mockup. After placing the image on the right place, the image jumped in some random position, please watch the video.
Nudging the image with arrow keys doesn’t work, too. Restart didn’t fix the issue.
PS. I tried to insert the image from clipboard. Importing to Assets and inserting it from there fixed that issue.
