SILePER,
Hmm... It may look like crap, but just for giggles, try setting your resolution to 1024x768 and see what it looks like. I'm assuming that 1366x768 is your max resolution for your computer/laptop/surface.
Also try compatibility mode to force 640x480 resolution.
Neither of these would be a fix, but if one looked like it worked, it would be a clue towards a solution.
AC will run off of a USB key. Maybe copy it to a USB drive and see if it runs ok on another computer.
Regarding WINE, I haven't played with that for 5-10 years or so, but I suspect it should work. There's nothing really intense about the Adventure Creator that I think would slip WINE up.
I will say, the vertical minimum for the AC window is 900 for me, so having only 768 could be a problem unless you run your screen in portrait mode, if that's an option. Give it a try if your system supports it.
Of course, I think it was all my feature requests that bloated the vertical for AC from 768 to 900 pixels.

Maybe we can sweet-talk Tlaero into making an alternate widescreen mode.
Tlaero,
Speaking of requests, here's another one for game view, but if it's any kind of hard at all, don't bother with it, because it's not worth much effort.
I've come across a few instances where it would have been nice to be able to see the current image filename listed in the Game View, maybe as a note between the HTM page file name and the Preload/TopText.
Since my image names usually match my page names, it would be a fast check as I scan Game View to make sure I'm using the right page with the right image without having to load the page in the main AC window and look in the title-bar.
