Dear,
I think it like you said, it didnt load.
I created a customer contact named Harry for example in CRM module to log call, meeting…
I hope that when there is a sale from Harry, I can create an invoice, and payment in Accounting module. However, when I access Accounting module, I didnt see any contact, in this case Harry. Then I cannot do anything in Accounting module.
For example, Cannot add new Customer in Accounting module.

I have tried in both version 1.5.t and 1.5.11.

Please support me. Thanks for your help!
