HR P&F: Checkbox Issue on mouse over

Hi experts

I'm currently facing a big issue in production with check box UI element in form.

When an employee try to click check-box in form, its flickering.(Please find an attachmen)

We didn't had an issue in development instance but it's happening in Prod. system. Does anyone face similar problem before?.. Please advice, how to resolve the issue. I'm still searching for SAP Notes.. Any input, really appreciate

Thanks

Babu
