Does that "freezing" happen only within EPIC or also outside? Maybe you can whittle down the code you have to a small, self-contained program that we can run (and look at) to reproduce your problem?

We are quite good at guessing, but obviously, guessing will take longer for us if you are not always present here. Also, we lose interest after some time and look at shinier things. So you might want to either provide replies quicker or provide replies with better information that help us shorten the back and forth. But maybe, your interest isn't in resolving the error you get as you seem to have found a workaround by hardcoding the filename already.
