IE5 Timeout ?

Is there a way of increasing the timeout for IE5 (running on NT4.0 SP6a). I’ve tried a tip I read (posted to a similar question for IE4 but it didn’t work. This was a registry change to
HKEY_CURRENT_USER\Software\Microsoft\Windows\Current Version\Internet Settings
(Add a DWORDKEY called ReceiveTimeout
Edit the value – e.g. 120000 is 120 seconds)

I’d appreciate any help.
Thanks
