Traditionally, (as in 'my experience'), the problem with these lamps has been related to poor (as in loosely) fitting wick material, that allows liquid alcohol to flow from spot if angles downwards. I haven't used one in many years so I don't know what sort of wick stuff is available now.
As to your particular question, I'd be more inclined to think that, over time, the same capillary action that feeds an active flame would be active (through evaporation). More so than a poorly fitting top (but maybe that too). I'd try getting a little rubber or plastic cap - like those on some spout bottles. Not sure if you carry it around or it stays in shop, but you could also try keeping it in a zip-lock of some sort. Weigh it regularly to see if you're loosing fuel.
As long as you're ultimately good with the JGOI solution, why not have some science fun? If you take good pictures, you can always get a Journal article out of it.

This may be a dumb question but...
Does anyone have a way to prevent the alcohol in my shank-burning lamp (with the long neck) from evaporating over time when not in use?
Admittedly, this is not a HUGE problem, but rather a minor annoyance. I am hoping that someone with more ingenuity than I, has addressed it.
If the answer is as simple as: "Just get over it and fill it up!" will also suffice if that proves to be the case.
