I had some strange results storing a bunch of presets for Dim Pro in the Program Data directory. After I had saved them I went to the directory and only a random view would show up. I was using them, so they were there, but they didn't show up in the explorer file list. They show up now so It's all good now but that was weird.
One annoying thing is that I have to run SONAR as adminstrator to save in the hidden Program Data directory. It's probably better to store them in the documents folder so you'll know where they are when after the next upgrade.
Also I think F5 will rescan the programs so they show up on the drop down list in Dim Pro.
