I am using Win 10 Pro on a Dell Inspiron 660 Desktop with Intel i5 CPU. It was installed as an upgrade in place, not a clean install. I am also using Start10 from Stardock Software.

When I enable the Task View Button, the first icon in each row of taskbar is obscured. If I toggle the show task view off and then on again, I can then see the first icons in the taskbar, but they go away after any other application runs. Also, the task view button sometimes disappears along with the first icon.

I also have Win 10 Pro Insider Preview Build 10162 on a Toshiba laptop, and this problem occurs on the Toshiba as well.

I'd love to hear from anyone who had this problem and what they did to resolve it.
