Using this function in a client/server setup of Alpha Five (V12). The client machines use Outlook as the default mail program.

I execute the function as EMAIL_CLIENT_EXTERNAL("") and Outlook is started up successfully with the email address as the recipient. However on subsequent calls, Alpha Five hangs for about 60 seconds and then a MIME error occurs. It seems that if Outlook is already running Alpha Five can not successfully communicate with it.

Anyone else have this issue? Any known work arounds? Also, I've tested on a machine that uses Thunderbird as the default mail client and it works perfect on the first and all subsequent calls.

I've tried using sys_resolve_url ( and this works fine when Alpha Five is running on the client machine but when it is running off a server the default mail client must not be known.
