"Session expired" when clicking too fast

[Jos Geluk <..hidden..>]

Hello,

I notice that when I click two links on the menu sidebar rapidly in
succession, I get a "Session expired" warning. I need to fill in my
password and off we go again. With browsers remembering passwords, this
is not too much of a problem. But I don't think it should be happening.

This is LedgerSMB 1.2.21 running on a home server on Ubuntu 11.04. The
browser can be anything. The error is very much repeatable.

Any ideas?

Thanks, 

Jos.
