I've just updated Chromium to version 43.0.2357.65 and the value boxes are not working when the mouse is on top of the charts. I've also tested it with the "basic bars" example at: http://www.humblesoftware.com/flotr2#!basic-bars .. same result.
I'm running Chromium on top of Debian GNU/Linux.
Any workaround I can apply before the fix comes up?
Best.
