I'm trying to take a screenshot through the "Screenshot" application and I'm not getting the save dialog. Basically, this article describes exactly what I'm doing except the save dialog doesn't show up. All of the printscreen shortcuts don't seem to work either.
Any ideas what issue I might be facing? I've looked pretty extensively for a new png file:
find -maxdepth 3 -name '*.png' -exec stat --format='%Y %n' {} \; 2>&1 |sort -n |tail
