BPM Object presentation collapses and disappears, UNDO disabled

Question

I got a problem with BPM5.7.
During a presentation build I created a number of tables and inserted labels and controls, but after I inserted new table and clicked in a cell entire presentation collapsed and transformed into page with a Header and 2 Buttons (Submit and Cancel) only.
“Undo” button got disabled and I lost my 2 hours work. This is the 4th case of same behavior and 3 times I just rebuild presentations (they were simple).
I need to understand how to eliminate same problems again.
Thanks

Hi,
Stating the obvious here, but it looks like you've collided into a bug and you're able to duplicate it only after a couple hours of hard work.
Over the years, I've gotten into the habit of saving frequently when I'm editing a presentation.
You probably have already discovered that presentations are pesky in that you usually have to manually click the save icon with the focus still on the presentation for any changes I've made to take effect. I'm wondering if this might be used to your advantage in this case. I'm thinking if you save frequently while editing the presentation and if (hopefully you never run into the bug again but if you do) you run into the bug, you immediately exit Studio without saving. Sure you've thought of this, but this way you'd lose only a few minutes of work.
Not a great thought, but only thing I can think of to get around the bug you're running into.
hth,
Dan
