Just updated to 8.1 yesterday. Since then, there have been issues.

If I left click on the Folder Icon in the task bar or right click and select "File Explorer" I will get the usual blue circle telling me to wait, except the window never appears. Instead the screen changes "purple" as if the metro start page is about to appear, then flashes back to my desktop and nothing happens.

If I right click on the "new" start icon and select File Explorer from there everything appears to work I can also click on the normal Folder Icon and select a folder that has already been opened.

Once opened, I can step into and out of folders, select files, perform tasks on them etc. Unless I right click and try to bring up the pop up menu, then the same thing as described above happens. This occurs on files or folders.

Not a show stopper but very annoying. Any ideas?
