I have been using Paperport for over a decade now, and there has always been a certain problem which I hope is fixable: When edition an image file in Imageview, after I have made many changes, then try to undo the last changes it undoes a whole slew of past changes, so I have t do the work over. This can take a large amount of time. This is especially true when I have made changes under "enhance", such as changing contrast. I am thinking that Paperport must be running out of memory to hold all the changes, so just discards some. To avoid this problem, I have to exit Paperport completely, then re-enter it, after I have made some changes. Just saving the file does not appear to reliably fix the issue. I am wondering if Paperport could give me some warning shortly before running out of memory or use a bigger memory buffer so the problem does not arise. Anybody else run into the problem?
