Hi iDreDushka!
Thanks for sending along the new video. When the cursor is being dragged past a guide quickly, the dragged cursor is less likely to snap to the guides you are passing. Slowing down as your dragging cursor approaches the guide should help ensure that the snapping behavior is able to occur.
I would also recommend checking that “Snap to Guide” is toggled on! You can toggle guide snapping by navigating to “View > Rulers, Grid, and Guides > Snap to Guides” or by right-clicking on a blank space on the canvas or on the rulers.
If you are not currently using the most recent build of Axure RP 9 beta, please try updating as well. You can check for updates by navigating to “Help > Check for Updates” in the Axure RP 9 application.
I hope this helps!
