<p>Gee, I thought I was the only one who had this problem....My home PC, was home built, and to save the cost of Windows, I put on Fedora, well it's Fedora now... I create a Service on the home PC. copy everything to the church PC and the Powerpoint Barfs, unless I copy the powerpoint file and add it to presentations, then it works fine. I don't add presentations at home anymore, I just copy the file into the service directory with the service and add it at the church.</p><p>I think one of the issues is that the registry/config files are used for storing the presentation file links, which are then linked to the file somewhere. I think a better design for this, would be to copy the presentation file into the presentations directory and use an SQLite database to do the linking. It's a little refining in the design, the registry/config should be used for items that are machine specific, the data directory should be used for things that are installation specific. In other words, if I use two computers, I should be able to copy the data directory from one machine to another, and then run a service on the second machine, without needing to redo things.</p>
