I have seen the persistent send mail issued with FM14 I recently installed the 14.03 update and I am getting this error once MS Outlook 2013 (64-bit) opens. "This action cannot be completed because the other program is busy. Choose "Switch To" to activate the busy program and correct the problem." By clicking "Switch To" it just brings you to the desktop. It seems that Filemaker has not fully addressed the send mail issue in the 64-bit version of the product. This is causing an issue for my many customers that have been upgraded and caused me to need to roll them back to v13. Any insight would be greatly appreciated.
