Flashing variable in numerical field

Flashing variable in numerical field

Hello,
I have problem with fields where numerical values are shown. The project is made in Zenon 7.00 sp0.
On screen there are numerical fields with pressures, flows etc. Numerical values in fields are flashing when variable change value. It is very irritating for operator who is watching SCADA application.
Variables are spontaneous, connection with PLCs are good, no red squares in fields.
I checked monitor, monitor is good. Can you give me some answer what to check or what to do to solve this problem?
Regards,
Albert
