With the panel issue: open the panel.cfg and scroll to the bottom. Last-but-one section is:
[Default View]
X=0
Y=0
SIZE_X=8192
SIZE_Y=3500
If you increase the SIZE_Y value by 400 to 500 to around 3900-4000, then the image should fit the panel. Voila.
Regarding the 737 EXP expansion pack: some of it has now been superseded, so you don't need the fx files that are in there - they are for an older version of the engine exhaust system. If you've installed v3 (the latest version), then you already have what you need. The FD has been recently updated, so the only things that haven't changed in the pack are the repaints.
Now you're good to go.
