iSeries Navigator

["Angus MacQueen" <amacqueen@xxxxxxxxx>]

I have a user connecting to a V5R2 box using a fully patched V5R2 version of
iSeries Access, when he opens Navigator and authenticates himself he double
clicks on the server to open a connection and nothing appears. The same
behaviour occurs for any iSeries.

Application administration is not being used and the same problem occurs
even when I try with a more powerful profile from his PC, yet for everyone
else this is not a problem.

In an effort to solve the problem I upgraded his client to V5R3 (no service
packs) - still the same.

It occured to me it might be Java, but that was updated as recently as Feb
2007 and was checked for updates today, it appears to be the latest version
1.5.0_11.

Any ideas, anyone?
