Weird Mouse+Alt moving in editor

[FlawlessHappiness]

I wanted to study how the map-structure in 22_torture_chancel, but a problem happens to me:

When i look down on the map i am able to (While holding left mouse button and Alt) slide across the map left, right, forward and backwards, as usual.
But when i look from the side I can go left and right, but also up and down. This irritates me a lot, because it makes it much harder to move across the map. Why is this happening with some of FG's maps? Can i turn it off?

On the bottom toolbar of the level editor, click on a square labeled "LT" (lock camera tracking to grid). You will now only pan across the grid. ^^

In the level editor there is a button, "LT". This locks the camera to the grid. I'm sure you know it's there, but maybe if you turned that on in that level maybe it helped.

Is it the level with the rope? Or is it with _redux at the final? Because I think I've learned how to make a rope in there

Heheh, ninja'd. ^^

No i'm just look at how they builded the hub you know?
And thank you MyRedNeptune! Never thought of that!

Spoiler below!

Keeping the camera locked to the grid is very useful for making normally levels, they put the option of dis-locking it so you could make ceilings and other stuff that was much taller.

Meh, in my opinion the only purpose it has is to get faster through the level in the editor, but nothing else.
