Windows XP and Vista
Sugar 5.1.0b
Apache 2.2.4
PHP: 5.2.3-1ubuntu6.3
MySQL Server: 5.0.45-1ubuntu3.3

I've installed a package that includes three custom modules. In all of them I have clicked, "Navigation Tab" but none of the modules show up at the top as tabs. I looked in "Configure Tabs" to see if they are just hidden, but they aren't there either. I did a quick repair and rebuild but that didn't seem to help at all.

I'm not sure if it is the version of sugar I am using or what, but it seems to have a ton of problems. In addition to this problem I installed a module today that was related to two other modules (candidates and positions) and its subpanel isn't showing up in either place. Am I just using a bug-filled version or should I continue to expect this while using sugar? Its very frustrating to find that things often don't work as they're supposed to.

Any help would be greatly appreciated.
