[news.eclipse.platform.swt] Problem launching Eclipse Help system from S

[Phil Blake <phil_blake@xxxxxxxxxx>]

I have an SWT app which launches the eclipse Help system from app Help 
menu and this all works fine, until I run the SWT app from another 
userid, and then the Help.start() request fails.

Running the SWT app on Windows XP, if I give full-control to the defined 
userid to the <eclipse_home>/eclipse directory, then all works fine.

I don't really want to give full-control as above, but using the 
-config, -data, -noexec and -Dosgi.locking=none options, then the 
Help.start() doesn't fail, but seems to hang and never return. (This 
"hang" is also seen on Linux RedHat).

I have tried using the -consolelog and -debug option to see what's 
happening, but this gives no clue to the "hang". I have also tried
setting the port= and host= properties in the help.appserver 
preferences.ini file.

Thanks,
Phil
