#69 Crash when resuming a session

[Jesse Harris]

When closing a session on Windows 7 64-bit, the Open NX X Server process (Xming.exe) does not terminate. When trying to open a new session, Open NX will crash.

This may affect other versions of Windows or platforms, but that hasn't been tested. I've seen this affect two separate systems with the exact same behavior. One is using Windows 7 Pro 64-bit, the other is using Windows 7 Enterprise 64-bit.

Expected behavior: Xming.exe should be terminated when suspending a session.

Actual Behavior: Xming.exe is left running and causes the Open NX client to crash when attempting to resume a session.

Steps to reproduce:
1) Start Open NX and login as normal.
2) Click Resume when you receive a prompt about an existing session.
3) Close Open NX and choose the option to Suspend the current session.
4) Repeat steps 1 and 2. Note the error message.
5) Open Task Manager and look for "Xming.exe *32". Terminate the process.
6) Repeat steps 1 and 2. Note that it now works as expected.

Note: you may need to repeat these steps a few times to reproduce the behavior.

Workaround: Do End Process on Xming.exe and new sessions will start to work again.
