I had Flex Builder 3 installed and working properly.

I then downloaded Zend Studio 7 (Eclipse) and installed the flex 3 plugin for it. Since doing that I now have a problem with Flex Builder.

I right click on the Flex project and select "properties->build path" there are now missing options. I should be able to add project references and SWC's. These options are simply missing. I basically get a blank window instead of the options.

I have tried completely removing both Zend and Flex Builder. I re-install Flex Builder and it's still the same.

This is on a Vista Ultimate system. I have tried running the installer as Administrator.

I've been trying to find if there is a way to do a clean uninstall of Flex Builder, can't find how to anywhere.

Any ideas?
