Monitor program with a separate thread

[Dean_Reedy]

I have a Vb 2005 program which is connecting to a GoldFax server using a dll. This vb program connects to the Fax server and sends data telling the fax server to send a fax and what data to use. Basically is a connection between fax server and legacy Company software.

The problem is that the program locks up about once every two days or so for no apparent reason. If I stop and start the VB program then everything is fine. It locks up during making the connection to the fax server. The whole program locks up and you can not press any buttons or anything.

My question is, if I start another thread that monitors the Program will that thread lock as the rest of the program locks up?

Thanks,

Dean
