I *did* do some messing around with JDKs and JREs - mostly just deleting 
old ones but I did tinker with environment variables a bit (but NOT 
classpath) - several days before this problem began and had some issues 
then, including exit code 1, but I cleaned those up and Eclipse was 
working fine for several days.

That's an idea no one else put forward. (I found one FAQ telling me to 
make sure my hard drive isn't full and it's not even close so I was able 
to eliminate that as a possibility.)

I just went into eclipse.ini and increased the memory size from 1024M to 
2048M, then launched it via my desktop icon. It made no difference at all.

I tried his suggestions but they didn't work.

I've tried that but I'm not getting anything displaying at the command 
prompt and no logs are getting generated either. (I'm looking in 
eclipse\configuration and the only logs in there are from several days 
before the current problem began.)

I feel sure this is something very simple but I'm darned if I can figure 
out what else to try.
