Quote Entry Freezing When Opening a Record

My Company is going to be doing an upgrade from Epicor 10 to Kinetic and we have set up a test environment to test out our customizations.

Every time I type in a quote number and hit enter Kinetic will freeze up like this and I have to use Task Manager to kill Kinetic (it does the same thing if I use the record search).

Anybody have any suggestions? I have reinstalled Kinetic several times and am out of ideas.

That looks like a pretty heavily customized Opportunity/Quote Entry screen… so at this point it needs some troubleshooting. Go into Customization Maintenance and run Verify Customization on this… see what it tells you.
