run is known to crash at random occasions, since... around that time.
I don't know if it has been fixed, sorry.
That aside, I see no reason to use run in your case.

Use cron, then there won't be any stray windows.

Now, THIS is a VERY wrong way to do it.
You're
1. Starting run
2. Telling it to start bash
3. Telling bash to start xterm
4. In which you're starting an SSH session.

Why not start xterm directly? Also, ever heard of PuTTY? Or mintty?

Most simple solution would be to use right tools for the job, I'd say.
