1. Actually my interest in mapmaking was revived when I saw a couple of days ago a post that said some things about mapmaking for hire. And thought someone could help me build "elevated" buildings in SP. That's when I decided that I should install SP and fired up this map editor (I'd been living for a couple of months without SP installed). I noticed this problem quite so many months ago yet dismissed it as trivial problem because I had become disinterested in mapmaking back then. So, yes, I'm sorry for not reporting this quite earlier. Actually, even now, I don't really care about that skewed screen bug.

2. The real issue for me to not fully utilize the map editor is the "sluggishness". The scrolling is, although still navigable, somehow slower than the in-game map editor. I don't give a damn if it's using resolutions other than the desktop, but this slow scrolling is "unbearable" to me. It's not that really slow by the way, it's just not as smooth silk as the main program would scroll, as if it's waiting a fourth of a second before continuing the scroll. And this scrolling problem isn't tied to resolutions or windowed mode whatsoever. It's just the map editor itself.
That's why I didn't fully use the map editor for many months. For map drawing, I used the in game map editor. While for copy pasting map etc I used the extended map editor.

3. I didn't assume nor said that it's sluggish for everyone. I was just reporting what I feel about the map editor. And yes, I can assure you, my system should be able to run this thing very smoothly, and thought "probably" this has something to do with the program itself:

-AMD Phenom II X6 1055T 4 GHZ.
-8 GB G.Skill Sniper memory 1600 MHz CL9.
-ATI HD 5770 (this one I haven't updated to the latest driver, possible culprit?)
-Windows 7 Ultimate 64 Bit.
-1 Terabyte Hard Disk. With LOTS of free space.
-DirectX 11.
-Steel Panthers installed to drive G with the latest patch installed.

Thank you very much.

EDIT: Answering Andy; Yes, the game itself runs perfectly smooth in windowed desktop resolution. But when I set it to 1600 x 1280 windowed mode, it would display the same skewed screen problem. Other resolutions are fine though.

So, to sum it up:

1. The skewed screen problem happens in both the game and the extended map editor.

2. The skewed screen problem only happens in the game if set to 1600 x 1280 Windowed. Desktop resolution is fine.

3. The skewed screen problem happens in the extended map editor if the game resolution is set to desktop (i.e 1366 x 768) or 1600 x 1280 Windowed.

4. The "sluggishness" problem happens only in the extended map editor, regardless of screen resolution. The game itself, and the in-game map editor, run fine and smooth like a silk.
