Hello, there is no evidence of explorer.exe crashes.
I noticed that, if I boot my pc without secondary displays connected, the desktop shows up normally and there are no lags nor explorer crashes.
As soon as I connect another display, explorer hangs for about 30 seconds and later the date/time position issue could appear.
One of the reasons I use Start11 for is the small taskbar, so I cannot use the taskbar size as workaround.
Thanks for your help.
