Problem with MicroStation SS3 in Windows10

I just updated to Windows 10 and MicroStation and Bentley Map are behaving quite strangely.

Before I continue I should tell you that my colleague also updated to Windows 10 and everything works fine.

What has happened in my case is that suddenly all MicroStation and Map icons have administrator badge attached even though I'm working on a user with administrator priviledges.

Another thing, and more annoying, is that when a design file is opened in MicroStation or Map all kinds of lines appear:

These seem to be some kind of "ghost" lines as they do not appear when printed and cannot be selected or worked with. It's like the can be seen but aren't there. When all levels are turned off the lines disappear.

Is there anyone who has had a similar problem or is there a known solution?
