Hi no the floating bar is on all windows machine i did try(all are W10 IE11), i have 2 in my home, also my dads laptop and my ex wife laptop has the same floating bar but also all my other problems.
It is only when i'm logged in, when i used it as a visitor there are no problems but then it is also useless fir me.
And also opening Rebrickable.com main page takes more as 10 to 15sec in V3 and when America is awake rebrick is often offline.
Online the cloud is there but says no connection could be made do to server problems with rebrickable.com will post a screen shot when i have it.
In V2 it has never been offline, and the main page was allways there in a second.
I think I might have had this issue in pre-beta testing, but not the floating black bar. I just added a couple blank lists to make mine 27, but couldn't duplicate your problem. I'll check with Nathan to see if having more than 20 lists in v2 is causing the problem.
Could the floating bar be caused by your resolution settings? I know if you are like my Mom, you need really low resolution to see things. Try increasing your resolution (or 'zoom out' on a Mac) to see if that gets rid of the floating bar.
It's ok, I made it to level 5 quite quickly once I started submiting some change. I did not expect the points to go up that fast. The large numbers scared me a bit originally because my first actions only gave 1 or 2 points. I'll have to do a photo session with my old parts.
