From what you described I dont see it ever working at all. I must have missed something.

I think you misunderstand proxies.. A HTTP proxy is designed to fetch web pages and other data from web servers. Your phone says to the proxy "get me the following file: (a web page or download, image etc)" and the proxy gets it and sends it to the browser
IM and VoIP use COMPLETELY different connectivity to the internet. Unless your IM program has an option to connect to a web server and send it data then it WONT work with an HTTP proxy! HTTP is web only! Most IMs and definitely most VoIPs dont run on HTTP
Maybe, they could use the RTSP proxy that you can also set in the conenction options, but then you need to have a proxy that understands RTSP..
The whole point of providing a closed network at work, an HTTP proxy and then making all the web traffic go through the HTTP proxy is:
a) no other traffic (msn, jabber, skype, voip, im, ftp, vnc, remote desktop, time protocol, telnet, sqlserver etc etc [the list goes on.. hopefully youre getting to understand that there is more to the internet than just web/http) can get out. This stops your workers sitting on their assk chatting all day
b) you can control which sites they go to by having the proxy deny the access
Now, lot of things sprang up around HTTP (like web services) because they were suited to work over HTTP and existing firewalls didnt have to be reconfigured. Sometimes there are ways of tunneling data through an HTTP proxy so it can connect to another service that is not HTTP, but generally you cant.
You can generally ONLY run applications that know how to use the HTTP protocol to do their work. MSN Messanger CAN use http to work for example but exactly how it does it is beyond the scope of a forum posting

As root edit the file directly.
First cat the file to look at its content:
If the http_proxy line exist, use leafpad to edit the fileCode:cat /etc/profile
Code:root leafpad /etc/profile

iirc you've the backup of this file. Just copy it back.
and re-edit it again.Code:cp /etc/profile.tmp /etc/profile
BTW, It's strange that i don't have the display problem when using 'root' instead of 'sudo gainroot'.
