Graphical Stats funny behavior

[Craig Austin]

Hello,

I just installed the latest version of eventum (1.6.0).  When I log in and
see the intitial "Graphical Stats" page, most of the graphs don't show up.
(There is just the little box with a red x in the middle, like a graphic is
missing.)

This happened from time to time in 1.5.4, but I was usually able to refresh
the page, and solve the problem.  Now, no matter how many times I refresh, I
still get some graphs missing.  It's not always the same ones either, it
changes.

Any ideas?

Craig
