1.5.2 Watermark gets repositioned constantly during resizing

[XnSoldier]

Viewer - Watermark Function.
I am using various PNG watermarks with transparency. When I use the top middle box to resize the Watermark it gets constantly repositioned further to the top. Keep dragging the anchor and resizing larger/smaller to see the effect.
This happens only with the top middle anchor box not any other one.

top middle anchor??

[XnSoldier]

There are four "anchor points" (aka little boxes) to resize the watermark.

few more issues:
- similar issue during resizing via left anchor point
- watermark start to flicker during resizing once anchor point moved behind opposite one

anchor are not like that?? Paint module in XnView MP?

[user0]

no such issue in Draw mode
also anchor controls are different in Viewer and Draw modes, guess they have to be unifed
