I don't ever have this problem on my machine (MacBookPro, OSX), but my partner has it quite often on his (Dell laptop, WindowsXP):
In our app, we call FileReference.browse for the user to select a local file. I've got a that call as basically the only code in the click event handler for a button. On my partner's machine, he clicks the button and sometimes has to wait a minute or more before the OS open dialog shows up. I'm not sure what I could be doing to affect the amount of time it takes for the OS dialog to show, and it may just be a quirk of his machine. Is there any way I can fix this, or if not, handle it gracefully? Troy.
