Hello,
I'd like to ask something regarding this issue where some user are unable to do anything after opening Purchase Order Menu
Even clicking back arrow not working.

What have I tried
- Delete user personalization
- Clear Browser Cache/Cookies
- Recreate user
- Change User Permission as Super
- Enable disable javascript
It's still not working, and Im at lost how to solve the issue.
When I login using another user, it's working fine.
Is there any suggestion regarding this issue?
