So, took a leap of faith, testing Dynamics CRM 4.0 on IE9 BETA.
These are the findings:
seems to work fine, except for the dashboard graphs, which do not display.
Lead creation works fine.
Lead editing works.
Lead conversion works, to Account, Contact and Opportunity.
Created Quick Campaign – works as expected.
Creation of new Case works.
Functionality is there, working as expected. On the dashboarding side though, minor problems rendering graphs. Will have to investigate further. If anybody has the fix for this, spare me the time to research it :)
I will be testing this shortly with the CRM 2011 BETA version also, which is definitely more graph intensive.
