I made the video: At 0:36s I klick on the little triangle next to my project name in the Journal Editor. At 1:14 a white border appears around my project name. I assume it is now selected. 38 seconds!!

And it`s just the border. All the subitems below it haven`t shown up yet.
At 1:38 I double click my project name. At 1:53 the subitems appear. 15seconds for that.
At 1:56 double click on Quest Categories. 2:14 the subitems disappear!!! WTF????
This happens at least one more time.

At 3:23 after several double clicks on the Quest Categories I wait.
At 3:34 the Quest Categories Content is finally shown on the right panel.
11 seconds. But it`s unusable because the input fields are too small.
At 3:54 the panel finally looks like it should. 20 seconds to load that.

At 4:07 I try to delete the filler text in the Category ID.
At 4:54 it finally is gone.
At 5:14 the first part of my Category ID is visible.

At 6:14 I input the description.
At 7:14 the description field shows what I typed.

When I close the journal window it asks if I want to save the changes. I save them and reopen the Journal Editor. The description has not been saved.
