rotate problem seen

[Max-C]

Good morning to all,
I have been having a problem with the rotation of both parts and assemblies for a few days.
for example, I place myself in front view (plan x/y). if I reward the mouse wheel to turn back to x it makes me turn only 90 degrees and not 360 as I always did. problem that persecutes me acneh if rough around the axis z allows me free rotation instead around the axis y.
Can someone help me?

thanks in advance

solved: you happen to go on the three Cartesian axes at the bottom left->cut dx->togliete check a "wheel around the vertical axis"
