I did some tests with MySQL and I spoke to the customer, the problem is
different as I wrote, I am sorry for that.

Switching from week to week is sometimes fast, sometimes about 3
seconds, not 20.

The biggest problem is that when you switch from week to week, sometimes
there appears not one, but two menubars on the top. Then you cannot
switch anymore from week to week. After a refresh from the browser it's
OK again, but it's very irritating.

What could be wrong?
