Version 1.0 64bits (Apr 28 2022)
The image doesn't move when a selection is dragged against the following window edges:
- The left and right edges when XnView MP is maximized
- All edges when XnView MP is fullscreen
The issue doesn't happen when XnView MP is unmaximized.
Because the image only moves when the selection is dragged past the window edges.
Effect:
Nothing happens
To reproduce:
1. Start XnView MP, maximized
2. Open an image that's larger than the monitor when the image is zoomed in to the middle
3. Zoom in to the middle of the image
4. Hold down the left mouse button to start drawing a selection
5. Move the mouse against the right window edge
Actual behaviour (bug):
Nothing happens

Expected behaviour:
The image should move to the left, so that the selection includes the part of the image that was outside the window's right edge.
Just like it does when the XnView MP window is unmaximized.
A possible solution:
Maybe the image should start moving when the selection is dragged within a couple of pixels from the window edges.
Notes:
The issue only occurs on the window's left and right edges when XnView MP is maximized.
It happens on all four window edges when the window is fullscreen.
If you're using multiple monitors, then the issue doesn't happen on the window edge, with another monitor past that edge.
