uigetfile does not work in a loop

I am running the code below to generate a list of files separated by spaces. If I put a break point in the while loop or step into the loop using a break point outside the loop, everything works correctly. If I run the code normally by calling the function it is in, it never opens the uigetfile window. I have put a disp('Hi') in the loop after the uigetfile command, at it does display the text in the command window so the loop is running. How can I get this to work without stepping through it?
RelatedFiles='N/A';
FileName=1;
while FileName
[FileName, PathName]=uigetfile('*.*','Select Related Test Files (Press Cancel when Finished)','MultiSelect','on');
if ischar(FileName)
FileName={FileName};
end
if iscell(FileName)
for I=1:length(FileName)
if strcmp(RelatedFiles,'N/A')
RelatedFiles=[PathName,FileName{I}];
else
RelatedFiles=[RelatedFiles,', ',PathName,FileName{I}];
end
end
FileName=1;
end
end

Are there any EVALs in your code, which redefine built-in functions? In debug mode, variables created by EVAL are handled differently than in non-debug mode.

It works as expected for me in R2012b. Put "echo on" at the start of your code, and take off the semicolons. Then examine the command window and see if it did every line. And if you have disp('hi') in the loop, does it just print that millions of times as it goes blasting through the loop not waiting for uigetdir()?

Weird that echo on fixes it. Are you going to answer my question about "hi"?

I ran into the same issue with uigetfile in R2012b. I fixed it by making a call to drawnow just before the call to uigetfile. ex:
drawnow;
[fn,pn] = uigetfile('*.mat','Find file');
Hope this helps!

Hi, I had this same issue before.
Sometimes matlab runs faster than figures can populate and it moves on to steps too quickly.
I can't remember if its before or after, but try putting like a 10ms pause before or after your uigetfile.
You won't notice the difference, and it will possibly solve your problem.
pause(.1)
