Hi,
1. Can you download the last Hikahsop version, install it, and test it again ?
2. If you still have this issue, can you tell me how, and where do you exactly have this issue ?

Thank you Mohamed - have applied the latest version prior to posting.
It is not consistent - will test and report back with more specific details.

*** EDIT ***

Well it seems that issue is no longer an issue - do not know what caused it OR what fixed it.

Thanks for your feedback .
