Hi modcom77,

I attempted to reproduce this but I was unable to get your results. If you could provide a short video or .gif of you reproducing the issue, that would be helpful.

Hi Jon,

Here’s a GIF of the bug:


Hi modcom77,

Thanks for providing that GIF. Does it still resize the entire editor window if you click and grab the edge of the Content Browser/ Output Log near the Output Log tab rather than in the center of the window?

No; it appears to work fine as long as the cursor is dragged to the left of the toolbar. However, dragging anywhere directly below the toolbar will trigger the bug.
