That feature is already there, it's helpful to study the Blue Iris help file, as it is indeed helpful.
Scroll with the mouse wheel, then left click and the hand appears and drag away.
First, place mouse cursor over the live image.
Second, scroll to zoom in.
Third, as mouse cursor moves over the live image now, it changes from a pointer to a hand; just hold down LEFT mouse button and drag the image around.
Thanks for the reply guys but neither of the suggestion you mention work for me.
When I zoom in I get a little magnify glass with either + or -.
Again, I tried both of you guys said to do and neither work for me.
I think I see whats happening, try going to full screen see if you can drag around, I can't.
If I click on a Alert recording and go to full screen I get the hand to drag around no problem, but this does not work the same for me in live view full screen.
Thanks again for the reply but unfortunately I am still unable to move the screen as you are.
I see the cursor changing to a blue arrow and also changes to a magnifying glass but again when I left click the screen nothing happens, no hand to move the screen.
I attached a short youtube video showing myself trying to left click for the hand drag feature but it just does not show up.
So some of the cameras are more sensitive to the cursor placement than others. At least mine are. Some just by taking the arrow ALL THE WAY to the edge of the screen and it will start moving, while others the hand pops up.
When your cursor changes from the magnifying glass to the arrow, take the arrow all the way to the edge of the screen.
Your cursor did not go far enough. Go all the way to the edge of the screen and the arrow will turn to the hand and then you can move all around. Or it should start panning that direction.
