Dear friends,
thank you very much to all that replied to my 'tabwrite bug' post. Indeed, Sven's solution is working well for me. I was trying to use the cursor as a way to explore monodimensional surfaces for physical texture control, and to have holes in it was not really the maximum.
Sorry for not replying to the thread. For some reason which I can't check right now I am not receiving the list's posts, so I had to go and scoop the archives in order to see the replies.
Thanks again, excellent response from the community!
