hi,
New Perforce user here. I am having the same experience as well. The ‘’ Submit Content” button will casue the editor to freeze. However, somehow I figured out that it will be fine if I do “Submitt Changelist…” using the View Changes window. This way the editor won’t freeze and will work as normal.
I am so confused at the moment because both Submit Content and Submitt Changelist have slightly different pop up windows. one without validation checked while the other does.
