Start menu closing constantly wth autohide taskbar on

After the update today like 90% of the time when I click the start menu and hover up to the actual menu it'll just close, seemingly because the taskbar is going into hiding.

Anyway I could fix this or will I just have to disable auto hide and wait for a update?

I just applied the update that came out today and so far see no ill effects from it. My taskbar is always hidden.
Until a few more members chime in whether it is the same for them, open an administrative command prompt
and type sfc /scannow

Report back its results after SFC completes. If it repairs anything do a restart.

SFC came back fine but I think having widgets enabled on taskbar was the problem, after I turned them off I haven't had the problem.

Nice :)
