My mind is almost blowing up with this.
Shouldn't dielectric materials show good reflections ?
I've tried everything with Lightwave and Max but can not get reflections.
Now, how can we simulate a look through glass with reflections ?
Does anyone knows or I'm just plain stupid and don't have a clue how this works ?

Erp: You can not control Maxwell dielectric reflectivity.

Maxwell (as it is physical correct render) treats glass's reflectivity according from the camera's viewng angle and its thickness.

If you can post an image we might be able to help you achieve the result you are after.

These two images have the same settings apart from one having a Glass sphere and the other an aluminium material.
Real glass always has reflections. This one doesn't.
I've tried to put grey maps in the reflection chanel and in the specularity but still no reflections.
Don't know what I'm missing.
Thanks andronikos

You will not get your reflections in the exact same place as they appear on the metal sphere (the red box refl for example) because of the glasses IOR. It does reflect properly. Also keep in mind the fresnel effect. You will not see reflections in glass when looking straight at it, but as the angle increases it starts reflecting it's environment. With this sphere these effects aren't clear because of the IOR.

This would be a pretty huge bug that's so far gone unnoticed don't you think?

Mihai Iliuta, it didn't cross my mind that this was a bug. But it did cross that I was (am ) doing something wrong, or at least not the right way.

I will give it a try on a flat glass, never the less, I would like to have some control on the reflections. There are reflections and there are REFLECTIONS in glass.

Thnks for your explanation.
