I heard great things about Electrum and decided to try installing the portable version (Windows) to give it a test drive. I then sent an imported address (18YiwUnAvDJz9eUss3DZGPrH7L8vi9ciDx) 0.01 BTC and things seemed to go well ... that is, until an unrecognized address (1JvojZKzuABZT5iCm6hKJnV7Lm1VQ8iaDk) debited the exact same amount the instant I sent it:

Thanks for any insight you can provide!
