I signed up for the windows insider today and low and behold it downloaded the 1803 (build 17133.1) version tonight 'Creators Spring Edition' The Fall edition was very stable so I hope this is the same
It took about 26 minutes to download the updates and install, It's still got the white search box, it used to be black but with updates to the previous version it went white, well it's still white with this version lol
Possibly the fix or patch has yet to come through before it gets a public release.
Just looking through it at the moment. Maybe others have had more time with it and I would like to hear your comments criticisms etc;
