Hi,
Long winded I know - but to get a wallet stable on Windows:
1. Get (download) a copy of Virtual-Box.
2. Set up a virtual machine running Ubuntu (its quite simple - lots of guides) - you only need about 20GB space.
3. Install Z-Classic (lots of guides available).
4. Install Swing Wallet.
5. Send coins to yourself.
You could also then run a node from the virtual machine and support the cause!
Note: - especially as you would be running a virtual machine - BACKUP YOUR WALLET - preferably to a paper or offline storage (you can just take note of your public and private keypair).
Thanks Scott! I will try that tonight.
It is a bit puzzling that you need to run linux to have a stable wallet on a WIN cpu. With the upcoming ZEN fork it would be worth having resources allocated to get it fixed.
