G'day People,
	I have found an interesting little problem with programming in C. I
have found a cure, but I would like to know the 'sanctioned' way to get
around this problem.

I want to extract the UserName from the Chooser. No problems, just use 
tempHandle = GetString(CHOOSERNAME), then how do I get the "string" from
the tempHandle.  The process I was using was
	 strcpy(tempString,PtoCstr((char *)(*tempHandle));
Great, this sets tempString correctly. BUT, the Chooser Name field gets
mangled because the resource handle is now in 'C' string format.
When the application exits, the resource map is saved and the System
becomes unstable (Got the 'Cant Load the Finder', bomb !!)

Now some questions.
1) Why the hell is the handle to the resource attached to that resource?
   Doesn't it make some sort of copy? At no stage do I explicitly use
	ChangedResource(tempHandle);WriteResource(tempHandle);
   Why is it saved then?
   My understanding from IM is that resources will not get saved unless you
   explicitly use the above process.
2) What is the best way to extract stuff from 'tempHandle' so that things
   like that don't happen?  I presume there is a nice 'safe' way of doing
   this.
