[ROOT] TPaveStats->GetTextSize(), SetTextSize() not working as expected

Hello,

	I am using root 3.05/05, RedHat9 x86, gcc 3.2.2. I wish to create a 
TPaveStats in an existing histogram to display some other data, but I cannot 
seem to get the size right. Here is an example:

I draw a TH1F and fill it with some random values. Then I get a pointer to the 
stats box with 
	
	TPaveStats *stats = h1->GetListOfFunctions()->FindObject("stats")

Then I create another stats box with the default constructor and make it a 
copy of the original one:

	TPaveStats *newstats = new TPaveStats;
	stats->Copy((TObject&) newstats);
	newstats->Draw("SAME");

Now I have an empty stats box. However when I try to add some text,

	newstats->AddText("asdfasdf");
	newstats->Paint();

the text comes out really, really tiny. So I tried to increase the size of the 
text:

	newstats->Clear();
	newstats->SetTextSize(2.5);
	newstats->AddText("asdfadsf");
	newstats->Paint();

I get the same tiny text. I tried values between 0 and 1, and values on the 
order of 10, and some larger values (the deafult value appears to be 1). The 
odd thing is if I do this:

	newstats->Clear();
	newstats->SetTextSize(stats->GetTextSize());
	newstats->AddText("asdfasdf");
	newstats->Paint();

I get nice sized text. I used stats->GetTextSize() in the interpreter to see 
what size the default histogram stats box was using but it said that the size 
was zero. Am I doing something wrong? Is there some toggle I have to set to 
be able to change the size of the text?

Thank you in advance.
