I agree, that can be a real headache. And Im not sure there is a perfect solution.
You could try a couple of things, though. One approach is to attack the problem of sweat building up. Silk glove liners help with this, as they not only absorb some of the moisture, they create a semi-slick surface next to the inside of the glove that helps with the hand-extraction process. As a bonus, the silk liners add warmth, including for those times you need to pull your hands out of the gloves to manipulate something small. Silk glove liners are available from several sources (such as wintersilks.com) and usually cost around $8. Buy two pairs.
The other thing you can do is spray your hands with antiperspirant. Im not kidding; that really works!
There are so many gloves out there that its difficult to sort through them all and say X or Y works. But I really like Marmots Randonnee gloves ($100; marmot.com). They have a Gore-Tex XCR membrane, Primaloft insulation, and a wicking liner that seems to keep my hands pretty dry. So I havent had many stuck finger" incidents with them. Outdoor Researchs Arete ($79; outdoorresearch.com) are a good multi-purpose glove with a removable fleece liner. So you can peel off the outer glove, then the inner, and that can help with keeping fingers in the right slots. Plus, you can carry spare insulationany good fleece or wool mid-weight glove would workand always have dry liners.
Youve got your winter gear, now get outside and use it. Away.coms ski and snowboard guide makes it easy to find nearby slopes just begging for fresh tracks.
