Texture Dimension Size Questions

[Flux]

I learned from experimenting that resizing the model texture but keeping the aspect ratio still works in game. However, when I tried opening the Model in Magos and viewing with Texture, the Model Editor stopped working. Changing to the original dimension of the texture makes it work again.
Question: Why? and is resizing the model's texture a good habit and does not contain any dangerous side effects?

Why?

Bug in the program? Ask the developers.

WC3 cannot load textures that are not a power of 2 from what I have read. Additionally the lower the resolution a texture is, the worse it looks ingame. A 1*1 texture would be a solid colour.

Ahh ok. So the only side effect is the loss of quality. Thanks Doc.
