Hi, first time on this forum. Thank you for developing this useful software
Now about the problem:

I was using QET 5.5.1 under WIN7, and the diagrams looked ok, as in the left side image (the PDF file), but after changing the OS to WIN10 all the diagrams got messed up, as in the right side image (the opened QET window)

What can be the reson why this happened, what can i do to be able to use the old diagrams as they where, when they were ok?

Hello,
I just started using this software and i have to say i'm amazed. Your doing a wonderful work. Thank you.
My questions are:
Is the Linux version more evolved than the Windows one. I'm using the WIN version now.
Is there a way to detach a conexion from one element and reattach it to another one so you don't loose any settings that you made to it, or you just have to redraw and redo the settings from scratch ?
