When I edit connections (right click on a connection and choose edit) SQL Developer hangs for a few minutes (maybe 5 minutes). Eventually the edit connection window opens and all works fine.
The same happens when I try to export data (run a query and then right click on the result set and choose export). It will take a few minutes for the export wizard to open and in the export wizard when I click on browse it will hang again for a few minutes. It looks like any time it has to access my drives it hangs. I am working over a VPN and have a rather large network drive - maybe this is a factor.
Any ideas how I can fix this. I don't mind if SQL Developer ignores my network drive and just uses my c: drive.
