I have noticed similar things as well; sometimes I have to reload to get interact cells to appear correctly.
The automatic evaluation of interact cells bothers me; I think it would be better if this was changed. Is it not enough to use #auto? - William's comments suggest things are more complicated, but if not #auto already provides the same mechanism. -Marshall On Oct 22, 7:45 pm, kcrisman <[EMAIL PROTECTED]> wrote: > > The automatic evaluation of all @interact cells is a feature. > > Do you wish that this did not occur, and that users had > > to explicitly hit shift-enter (or click some button) to "fire up" > > any interact?
