It turns out that the compos dialog boxes did not include works in progress, even though it was possible to submit works in progress to the compos. It was a simple one-line fix to get all compo dialogs to display works in progress.
The changes should be available in the next release, which will be on Saturday at the latest. I won't make another post when the release occurs so as not to clutter up the forums with another release announcement. Thanks again to Ubelsteiner for his reports, and I'm going to continue to fix bugs and add usability enhancements.
