Calling COM methods from a different thread

[viperpiper]

Hi

I've got a client app written in C++Builder. I've got a function in my main form which calls a COM method in my server. If I call this function from a button on my main form, it works fine. If I call it from a separate thread in my client app it doesn't work (I don't get an exception, and debugging in the server end has shown me that the COM method never gets called at the server end).

I'm using Synchronize within the thread to call the method on my main form which does the COM method.

Any ideads guys?
