how to resize windows

[42363673]

I've been using XnView for many years and made no change to the program, but today I found the colour balance adjustment window (and some others) to be automatically resized. These cannot be manually resized by any means I know. I installed version 2.43 and no change.

Please refer to “XnView v2.32&33 - Adjust dialogue box clipped” for the solution to this issue.
