MAPI thows Cannot change thread mode after it is set exception

[Gavin Jeffrey]

Hi, I have a windows form(c#) and I am using the mapi dll to read email from a specific account. my project runs from - C:\Documents and Settings\GJeffrey.LAWACTIVE\My Documents\Visual Studio Projects but when i try to ininitialize the mapi session i.e. oSession = new MAPI.Session(); in a class named Email and not on my main form it bombs out with this error. It seems to me that it cannot run this object because this object is in the following directory - C:\Program Files\Common Files\System\Mapi. If i declare my mapi session as the first thing in my class constructor(or onload of the form) it seems to run fine but then it runs from the second directory. Any ideas or thought as to how i can solve this or why it is happening??
