After reading our latest tech tip, Footsteps #45, one of our subscribers sent Mark this feedback/comment. It got Mark thinking a little further about this issue. We wanted to publish this extra information as "Part B" to the original tech tip so that you will have all of the latest insight on this topic:
Hi Mark,
How are you?
I tried turning off the planimetrics toggle first and then right-clicking Book1 (without setting it as active) then closed it. So now I'm left with just one Fieldbook active. When I turn the planimetrics toggle back on my lines are back! I don't know why but it works for me ...

Here is the Zen Dude's response:
Hi Rex!!
It's nice to hear from you!
Your feedback made me look at this a little bit further, and I found out something else about this.
First, this tip (Footsteps #45) was really aimed at a work process where someone had created a temporary or secondary fieldbook just to review some data, and then after looking at it, closed it and went back to their first fieldbook. If that sequence is used, the issue and resolution that I mentioned holds true.
Using the sequence that you describe, this display issue doesn't occur. But I found out why. I seriously doubt this information would mean much to most people, however the programmers probably could use it to fix this problem. Your statement, "I tried turning off the planimetrics toggle first..." made me discover something I hadn't noticed before.
Say the first fieldbook had the Planimetrics and Codes toggled on. And then another fieldbook was created, set active, used, and closed. Going back to the first field will have trouble displaying anything that was toggled on when the second fieldbook was set active. So, it seems that whatever display toggles were on (on the first fieldbook) when the second fieldbook was set active, those specific displays won't be able to be displayed when you go back to that fieldbook unless you follow the process that I described in my tip. But if you toggled everything off before you went to the second fieldbook, everything would work fine when you went back to it. I know that if I had 10 fieldbooks open, each fieldbook remembers the display toggles that were on or off.
It might seem like the display toggles should apply themselves to whatever fieldbook is open, but it doesn't work that way. Each fieldbook retains a memory of the display settings when another fieldbook is set active, so that when you go back to it, it displays just as you left it. InRoads Survey obviously has a problem remembering its display settings when it's the only fieldbook. In fact, the bug is somehow tied into this memory - anything turned off, can be turned on, but anything turned on can't be turned back on ...unless you follow the procedure I described.
That really wraps up that issue for me!!
Thanks for the feedback!!
Civilly yours,

There is only one Mark Ditko. We need him for future training. I think he could help iron out some of the problems in the department.
