Need help. erZBrush problem


#1

Hi there guys.

So I’m busy building my character in zbrush and topology-ing it.
After 2days did open my fail to continue my topology, however when i hit edit topology my screen seem frozen. Well frozen might not be the good word but there is 1 vertex selected and if i move my mouse there is a red line from this vertex. My screen rotation does not work correctly so I cant continue my topology.

Would be gratefull if you can help me out. Dont know if an option is selected, atleast not something that ive changed.
