I was about to post the same thing.
Build 1603
Like Rod, on form save It feels like AwareIM has skipped a step somewhere & crashes my form, the Visual Perspective tabs have diappeared, form heading gone & buttons gone.
I have a HTML save button & when I press it to save the form I get an error message:
<Object Name> has been changed by another user. Please get the latest version of the data and try again.
In Build 1602 the form saves fine but it takes 3 seconds in 1603 it takes 2 seconds then crashes.
