Hi Felipe,
Today I set the embedfirefoxbrowser, and I tried many times Add/Remove objects to/from workspace, so far no white screen issue occurred, but I found the server is easy to offline and remind me to select if switch to offline mode, after click No, it can be back to online, I am not sure if this config option affect it.
My company don't have a plan to update the datecode now, we current use Creo2.0 M080.
Thanks!
Rick
