I'm afraid that is not possible. It could be made theoretically, but you will loose important features which work on selections (which is normal Windows behaviour). So, or the selections are undone by it (your double click), or you just shouldn't have them.
Why do you think this is important ?

PS:
Over at CA you were talking about .wav sounding better than .aiff for hires;
Do you have a means to check that the ouput from XX indeed is the hires you expect ? I mean, I just wonder whether the aiff -> wav conversion goes allright regarding this, since I really never tested it (nor do I have the aiff hires material).
