Files other than Images Question

[dcpaq2]

Group,

When uploading files such as MP3's, PDF's, WAV's, and etc.

Why is it that with an image I only have to click on it once to get the first image (intermediat in my case), but when I click on the thumbnail for any of the above file extentions I have to click on it twice????

Can anyone explain why it is doing this and is there a way to disable this so I only have to click on it one time before I get the pop up box asking me if I want to OPEN / SAVE / or CANCEL ?

Any help suggestions or ideas on this issue would be greatly appreciated.

Thanks in advance.

Doug
