Oracle Forms

Has anyone got Forms to work using the Sun 1.5 JPI on Vista using 10.1.2.2 app server?

I know 10.1.2.3 is out now but for various reasons it will be a few weeks probably before I can get our servers patched.

I was just wondering if anyone else has experienced a problem where the IE7 process hangs (not responding) just as the Forms separate frame pops up. I should explain that everything works perfectly the first time the url is entered (and it downloads and installs the jpi correctly) - it is only subsequent times (eg. after the PC is rebooted) that it seems to hang. Uninstalling Java and starting from scratch seems to fix it until the PC is next rebooted and then it hangs again.

I am using the latest 1.5 patch 15 and the server is configured with the family clsid so anything in the 1.5 family is used.

This problem seems to be reproducible either logged in as administrator on Vista or standard user, using http or https and just about everything else I have tried.

If it absolutely will not work with 10.1.2.2 then I'll give up and spend my time on the 10.1.2.3 patch but if there is something simple that I can tweak to get this working then that would be preferred at this point.

Any help would be appreciated. Thanks,
Alastair
