Problem with Message Control

Problem with Message Control

Hello,
We are experiencing a problem with the Message Control on ZenOn 6.51 SP0 Build 5 Runtime. The host station uses Windows XP.
When the Message Control is active, the whole application crashs when the system is trying to send SMS or phone calls, even if there is only one call or one SMS launched at the time. The mouse click seems deactiveted, we can not click on the buttons, but all the other values, caught by the other drivers like IEC61850, BeckhNG, SNMP or OPC are still refreshed.
The only solution found is to kill the ZenMsgSrv.exe process, in order to be able to control and click on the ZenOn Runtime project.
We tried to change the whole hardware solution : computer, SMS-GSM modem, but this bug still remains.
As the bug is partly solved by killing this process, these questions came to my mind :
Does the main ZenOnRT process is idling while the ZenMsgSrv is active?
Can the ZenMsgSrv.exe process bug if there is a long queue for the messages to send?
The wierdest thing is that it is appearing from time to time, sometimes there are no problems, sometimes there are. And it seems due to the Message Control.
Tranks for answering,
Regards,
N. M. Blanquart
