EXCITING news for us Chrome junkies . I just found this page explaining how Google left a back door registry option available to re-enable the modal dialogs until May 2015.

The first set of instructions worked perfectly for me. Finally back to using Eloqua in Chrome
Hopefully Eloqua can re-write their code by the expiration date...
