Image posted is fine, not a thumbnail. Not sure why you were trying to repost the same image. Images posted on the forum are by default always in thumbnail mode. Click on the image and you will see what I mean.

As bigjx suggested next update will fix the problem (if it's the same problem.) You might need to downgrade WireShare in meantime.
Whilst you installed an earlier version java 8, you might possibly have two versions installed. I guess you could check your Add/Remove Control Panel to verify this. I don't know about these days but in the past Windows sometimes a reboot would see the java properly initialised (system's java pointers/references cleaned and corrected) after installation. Though my reasoning might not be accurate.
