The "panel jumping in the middle of the screen" belongs to TDW's UI's mods.
It's a dialog you should normally only get when you want to add hyper-markers to your map.
In this dialog you can add a custom text to the hypermark.
If you get this screen out of nowhere, then you've obviously done something wrong while installing your mods.
A common mistake people make, is that they don't dig deep enough into a mod's folder-structure.
You can check the correct structure, before you enable a mod in JSGME.
When the mod is still listed on the left side, you can R-click on it, and select "Explore".
This will open the folder-structure for you.
Most if not all mods will have 2 folders inside the main mod folder: "data" and "documents".
So if you Explore a mod in JSGME's left half, and find another folder with the mod name, then you didn't install the mod correctly, as the data-folder will be at least 1 level deeper.
When installed correctly, the Explore-option will show at least a data-folder.
(TDW's UI's main mod will show a data- and a documentation-folder, plus a bunch of dll's....these dll's will be installed into your main SH5-directory.
