In New Application Wizard could be added button for refresh of projects. The reason is, in some cases this is not refreshed.
Workflow:
1. Create connection to console engint.openshift.com
2. Delete all projects in connection
3. Open New Application Wizard from File -> New
4. Select connection
5. When you are asked to create project create it
6. Now you should be on New Application Wizard, but project is not selected
Workaround: You can click on Back and Next afterwards, so you can see now project.

I suppose this issue is caused with slower server response, so user should be able to to refresh projects list and maybe edit projects(if he enter wrong name...).
