IE error message

[vi]

I am trying to use the webviewer to look at a folder on a mapped drive. It works well, but when I try to open a picture in that folder, i get the following IE error message - running a system command on this item might be unsafe ... i can continue and it launches it - but it is just annoying.... I played around with security settings and the only way to I found to eliminate it is by enabling the 'launching programs and files in an IFRAME' for the Internet zone, i tried adding that mapped drive to my trusted sites and i worked with the settings on the local internet. Only enabling on the Internet zone does the trick, but it causes IE to warn me every time i start a browser, which is even more annoying than the error message in FM... any pointers?

thanks
