Hi,

i've got a PDF with forms and some Javascript calculations in it.

All working fine when being opened in Acrobat, but behaving buggy when it comes to the Mac Preview App. The forms are shown, but the buttons and calculations do not react on any click. 

I understand that this is an Apple Software problem. But is there any way i could at least show a hidden field that says "Javascript is not working here, please open me in Acrobat reader"? Or any other workaround that the user get's aware of this?

 

thanks,

Christian

Thanks - I generally go the extra step of making all of the fields hidden by default so they don't "show through" the layer in some PDF viewers and then make them visible in a JavaScript viewer but that's not absolutely necessary.
