Welcome to the forum
Rick Holland,
All forms of Desktop Alert should always display on top (foreground) in all cases including in full-screen mode as long as you have POP Peeper set to "Allow all notifications" in the "Detect Full-screen Apps on new mail event" in "Tools" > "PPTweaker..." > "Misc2" (top option).
What version of POP Peeper are you using?
What Operating System are you using?
Are you using the default Desktop Alert ("Tools" > "Options" > "Notification", option: "When I receive new mail" option set to "Display Desktop Alert" in the "Visual" settings area of the "Notification" page)?
Can you recall any changes you have made to your computer since the last time the Desktop Alert had been displayed as expected (on top)?
