0.99.7: Preview not updated when becoming visible

XnView: MP 0.99.7 - 64 bit
OS: Windows 64bit

In XnView browser when switching to the "Preview" tab, the preview shows no or the last image.

Effect: Preview shows no or wrong image

To reproduce:
1. Start XnView
2. Select thumbnail of image A
3. Click on "Info" tab to display the "Info" panel
4. Select thumbnail of image B
5. Click on "Preview" tab to display "Preview" panel
Actual behaviour (bug): Preview shows thumbnail of image A :bug:

Expected behaviour: Preview displays the selected image B. It looks as if the preview is only updated as long as it is visible but updated not when the preview gets visible.

Good catch; followed the steps and I was able to reproduce the erroneous behavior as well.

Correct. I can capture a screen video if needed.
