From now, I can't change it again: IE 9 re-set the previous configuration.
For example: now i have set in proxy settings "proxy.domain1.com" and port 8080. I try to change it in proxy.domain2.com port 8080. Click OK and OK again to close IE Options window. Close IE 9 and reopen it. Proxy "proxy.domain1.com" is displayed.
I have the same problem on my laptop with Windows Vista 32b, IE9 installed and FireFox 4.01 (as default browser).
I keep setting the proxy setting to "automatically detect settings".
Every time I log on the internet IE9 seems to reset it to unchecked (no matter which browser I am using).
My problem looks a lot like your problem tosdan78...
After that, right click the IE9 shortcut and run as administrator. Then go to change the proxy to check the result.
