I told this many times, but will tell once again:

forget about using Windows wallet for now. Unless the developer finds a fix, Windows wallet is useless (it was working years ago, though always was a resource hog, but it looks like it just cannot handle the current big bloated chain). I would really like to listen if anyone was actually able to run it successfully for more than a week... Anyone?

Use Linux. Consider this coin as Linux-only one for now.
