@Savannah it took foreverrr to save. I pressed save, baked a cake, and then came back and it was (finally) done. TBH, it always takes MS a long time on my computer to export as a .png. I always thought it was just because my laptop doesn't have a high processing power.
@Alenonimo I'm worried it'll take forever to copy all the layers. Earlier today the lag was slow I could hardly work on it. It got a little better, though. I'm going to keep trying to figure out what the problem is, maybe re-install/update the program.
@carloswebcomic wow that's a huge difference in size! I'll try that and see if that fixes the problem. I just need to go hunt down the box with the serial number now =n=
@KreativeConfusion I'm thinking it must be some kind of bug. It really is too strange. I wish I knew why it was happening, though :/
