I'm using Win7, x64
I use only Classic Explorer in ClassicShell 3.6.2
Explorer crashes sometimes press the button "Show Desktop" in the taskbar, when you close the window or browser.
Open windows, desktop icons, taskbar disappears temporarily.
I'm using the new version is always one year, it is the same.
I do not happen when you uninstall the Classic Explorer.
I hope to improve.
