This happens to me quite frequently with AgExpert Accounting (online version). I use a Mac and the mouse has the feature where a slight swipe left will take you back one page on the website which in turn loses the entire transaction you have been working on. Is there not a way to have a feature asking "are you sure you want to go back a page" instead of automatically doing so and losing all information inputted. and of course it only seems to happen on long / lengthy transactions or ones that had a lot of thought put into them.
