I just tested Ghostpress 2.2 on two separate Windows 10 PCs and the taskbar still gets trapped behind maximized windows. SumatraPDF, a freeware PDF reader, is one example. Ghostpress appears to be extremely sensitive to taskbar behavior, which is highly unusual. I've tested hundreds of apps on W10 and the only other times I've experienced this bug is if a game crashes, or forced to close via task manager. Perhaps it doesn't play nice with one of ClassicShell, 7+ Taskbar Tweaker, or ShellFolderFix?
