Topaz Video window not adjustable to fit screen

Topaz Video 1.6.1. macOS Tahoe 26.5.1

When launched the Topaz Video window extends beyond the 15" screen on the right side on this new MacBook Air M5. It cannot be adjusted horizontally using the window edge to fit within the display. Please fix this most basic issue asap.

Double-click on the top area of the window to automatically resize to fit your screen

Thanks Margaux, done. It must have previously been a macOS issue because the Topaz Video window on launching now fits within the screen and it’s easy to resize it the usual way by dragging a corner, or as you suggest.
