Sage 50c on Apple Mac

SOLVED

We did (several) fresh installations of Sage 50c 9.3.4 on Apple Mac, after installing Parallels.  The installation worked, after we switched off Real time protection.

However the softare is so erratic.  I deleted the company and re-created it from scratch.  We also disabled the advanced search.

The problem is on Customer and supplier documents.  We cannot select the customers/suppliers - message says there are no records... If you type in the cust/Supp code, it works.  When linking a supplier invoice to a purchase order, same happens.  " no documents", although we just created 13 records.  Problem started when started to Link PO to Supp_Inv.

Anyone with ideas on how to fix this please?

Thanks
