Hi Gerd & Rob,

I have setup a proxy server and port in the 'proxy' tab of global options dialog, and then switch to the 'update' tab, click the 'test connection' button, it says 'can not download release.xml'.
Then, I check the log file (debug level was enabled), and found the exception 'java.net.ConnectException: Connection refused: connect', so I guess this function must not support proxy settings.
I also check the source code, indeed, no proxy arguments pass to the HttpClient class (line 219 in file net.sourceforge.squirrel_sql.fw.util.IOUtilitiesImpl)

And there is a inconsistence with the menu item of 'software update' in Help munu, when I click it, it says my Squirrel is the latest version, although the same exception occurred in log file.

please check it.
thanks.
