Hi David,
I don’t know if you have found the solution, however i had the same problem.
The cause was the internet explorer version, we hadt the nine and the powerdesigner
portal is optimized for the Internet Explorer 10 and 11.
If you use another browser, see the versions:
- Firefox de la v26 à la v3
- Chrome de la v35 à la v40
- Safari pour Mac OS X v10.9 et v10.10
- Safari Mobile pour iOS v7.1 et v8.1
