If you use internet explorer (Any version) and it crashes at time of accessing Oracle Forms, the following step could resolve the issue.
- Disable 3rd party browser extension (Tools -> Internet Options -> Advanced -> Browsing)
- Deinstall all Jinit versions. (Optional but preferred)
- Cleanup IE cache
- Close IE broswer
- Open IE and access URL
I have tested this with AS 10R2 (10.1.2.3) and IE 6 and IE7 SP2.
