Hi,

I found a "visual bug" in Service Studio (9.1).

The following steps will make the columns overlay stay on the page and not dissapear after completing the resize.

1. Select a container to resize;
2. Start dragging the container size; (columns overlay appears)
3. Right click without releasing the Left mouse button.

The overlay is now always visible, no matter if I start resizing another container. Only after navigating to another page does it dissapear.

The attachment show the result of the bug.

I suppose you already have done so, but do not forget to submit this feedback to Outsystems :)
