Hi bigseb - how long are you waiting for it to complete the export?

With a large model like that it could possibly take a while for the exporter to crunch through the entire saving process.

While it is busy working it will look froze up like that and give you that "not responding" type message if you try to mess around with it while it is busy working.

If you look in task manager and it is still consuming CPU that means that it's just busy working away and you probably just have to be a little more patient and wait for a few minutes for it to do its work.

In v3 I want to make things look nicer when it's crunching away on a big import or export like this, instead of it appearing frozen but for the time being if it is crunching away just let it do its thing for a while.
