Best wishes to all!

Hoping for help with an that mystifies me.

The problem relates to using iTunes.

Using the library and making playlists is fine.
The problem begins when I visit the music store to make purchases.

I can launch iTunes, click to visit the store, and perform a search for a title.
Then the trouble begins!!

When I click on a tune to play a preview, the music begins, but I can no longer pause the music, scroll up and down, or re-order by name, artist, etc.
The whole thing freezes (but the music preview continues to play to the end).

Sometimes it releases again for a few seconds but after a few stutters, I end up going to Windows Task Manager, shutting down iTunes, and relaunching, only to go through the same grief again!

The longer the list of results in the search, the more likely it is to happen.

Don't know where to look, to fix it.

I know it's not an internet connection problem because the preview continues to play, and other internet service continue to work perfectly.

Is it Windows or iTunes?

Any advice or suggestions very gratefully accepted.

Thanks in advance and best wishes to everybody here!
