Any other info on this?

The visio file would be saved in your temporary directory, e.g. C:\Users\<username>\AppData\Local\Temp. When closing visio the LF client should prompt you to save the document back to the repository.  If not, this is a bug, but I haven't heard of any reports of edocs being lost like this.

I was struggling with this as well, especially as the file goes into a location that is a bit obscure when you right click and open the file for edit,  C:\Users\<username>\AppData\Local\Temp, why not in subfolder in Documents\My Laserfiche Documents\Temp, but that is a not on the side,

Easiest way that I have found to edit files like Visio is: check document out, will be saved in Documents\My Laserfiche Documents, and select to open document for editing immediately, edit the file and save it, print if you want to, close Visio, then in LF select check in and tell it to remove the file from the local computer, not saying this is the best or the only way to do this but it works for me, hope this helps
