Yes (hor fun/haw fun). To me, it makes it slimier and mushier. Not mash potatoes-like but not good eats. That said, if you buy the fresh packs (usually located somewhere near the chiller section) you have to use it the same day. If you put it in the refrigerator it hardens and isn't good either. They used to sell rice noodle sheets here (essentially before they're cut up into noodles), but if they got cold (eg, someone put them in the fridge), it just ruined it. peeling them apart is like peeling dried paint.

I used to make dumplings with my mom.and then we'd freeze them until ready to serve them... but it was just so time consuming. And for the price difference, it just wasn't worth the effort. So now I keep a tray or two in the freezer. If I'm hungry, just toss them in some broth (on the stove) and done. The only time I put dumplings in the microwave is if I can't finish them (sorry, yyznomad has me outclassed by quite a bit). But I don't notice the chewiness of them as long as they're in soup first. Definitely not an issue if they're steamed/pan fried and then into the microwave for reheating.
