I wanted to sign up for our company's retirement plan, which you no longer do with old-fashioned paper forms and brochures: you go directly to the plan manager's web site. I tried at $CLIENT (Windows XP) and at home (Fedora Core 3) a couple of times. No go.
I didn't get an error message when I tried to register, but it wouldn't accept my login later. I called their toll-free help line, but couldn't get past the VRU without a valid registration....
This morning I thought of something, and got myself registered! The key? Use Internet Explorer....
I had forgotten to even try that since I use Firefox everywhere now. I had gotten used to the lame "Works best with IE" banners on web sites, but to completely fail to work without any kind of indication of trouble is really, really, lame. I asked our plan administrator to call and berate the company.
