Invoice PDF prints values with no decimal point, STRAN not updating with values

neil

I have a client who has experienced the following problem on 2 occasions.

Customer uses batch processing, progressing from Delivery - Invoice
Invoices print out, but without the decimal place, so a £ 10.00 invoice shows as £ 1000

The stran file is updated with a record for the transaction, however no values are recorded, and the creation date is blank.

The sanal & snoml files are updated but with the incorrect non decimal place values

Opera II Version 7.20.20
Client PC's Win 7 64 bit
Server SBS 2011 Standard

Only starting occurring in last week, Spoke to support, said had 1 similar report, but no real idea as to what caused it.

Any one got a suggestion.
