Well.. if it crashes completely and leaves no remnant of itself (like an application-titled window), then here's what I suggest:
1. Go to
http://www.acrasoft.com/ and pick up a license of GroundControl (cheap)
2. Write up a simple macro which checks if the app is running, if not it simply starts it up again..
(Not sure here, but it's not unlikely that You can do a more advanced check, like whether a registered app (hung or not) is responding)
3. Create a job which runs something like "%GroundControl%\gc.exe -r MyRestarterMacro.gc" every 5 minutes or whatever...
("%GroundControl%" = directory where G.C. was installed)
Mission completed

I love this shit, I'm a geek with this kind of stuff... (as much as my time & money allows it)
