I have a form where I acquire images that are saved to PDF via ImageEnMView.
It works as expected as long as I stay on that form. If I close that form (I only hide it) and open it again, then attempt an Acquire, the Acquire starts but does not show the twain scanning messages (it did the first time around) however it does pull the docs through. At that point the code is stop at the Acquire line and will not progress.
I had a similar problem. Does your form have the property = fsStayonTop? Tries once following: application.NormalizeallTopMosts; and at the end application.RestoreTopMosts;
I did not have it set to 'fsStayOnTop' but I was doing ShowModal. I simply changed it to a 'Show' and that fixed it. That is some pretty finicky software!
That seems to be a problem ImageEn might want to fix??? That was a waste of a day questioning what I was doing wrong!
