Arrow angle in max- problem

[timmie]

Hello,

Im getting the problem that the angle of my move tool changed, normally it's like this:


Now i get this:


Im working with a loft, which i converted into a editable mesh.
This only is there when i wanna move a vertex which is close to a corner, or something that changes from angle.

Does someone know how i can fix this problem with the angle, so i can move my stuff again:S

Thx

Tim
