2 Frames and file system

[Robert]

Hi,

I'm having a big trouble. Any help is welcome.
The OS is Windows 2000. I have a asp with 2 frames. On the left I have a
menu and one of the options open the file system on the right frame,
using file://. My problem is that when a user double click a folder
instead of showing the content of the folder only in the frame the
content is showed in all the window, so I lost the menu on the left.
This problem happen in win 2000, in winxp i have no problem.

Help me plz, I've tried everything.

Thanks,
Robert.
