I don't know if I'm missing something obvious, but on my tablet I can't scroll when Wolfram Alpha gives me step-by-step solutions. This is consistent across all queries, so I can only ever see the first step. Sorry if this has been asked, but Google is giving me nothing.
I'm having the same problem, using Firefox browser on Windows 10.
I had the same problem. Actually something worse: I would see 'half lines', and the pop-up was completely stuck (check out the screengrab). I use Chrome on my PC, and I fixed this issue by clearing all my cookies.
I just hope this works for you as well!
Thanks Ramana. I went to try the same in Firefox, but strangely the problem had already cured itself. It may be that I had cleared cookies some time in the interim.
