WEB IDE and COM issues in Windows

The Web IDE has a hard time connecting to the Espruino. Most of the time when I connect to the > Espruino in the console I would receive Connect and nothing more instead of the
console outputting the double =undefined. When that happens, I noticed
when I click the upload code button I would get the upload status bar
but the code doesn't actually upload.

I have been struggling with similar issues when I am trying to connect through HC-05 Bluetooth from a Win 7 (64bit) machine with a USB Bluetooth dongle. there will be two COM ports created and they behave exactly as described above. If I manage to create a third COM port with outgoing connection it usually works fine. But not always. It can happen that I manage to create a third COM port that is outgoing but it does not work. I am thinking that the problem is related to the Bluetooth drivers on my Win 7 not really working with the HC-05, but I have no clue. I am following this discussion in hope of finding a clue to my Bluetooth connection issue.

I use Blutetooth settings to Add Device, HC-05 appears, then I get to type in the four digit code, I open the Web IDE and there are two COM ports, both incoming. I can connect but all I get is
Connected
then after a while I get
Disconnected
