That was what i thougth too. I did the test again on this computer with a different file. It was a truck model made in Lego's LDD saved as Ldr. singe part. It loaded in 2-3 minutess. I changed the file extension to mpd and it loaded within 2-3 seconds.
I do not know the program the other file was made in since it was downloaded from the net. But it proves that the same happends on different files. My thrird computer is out of order at the moment. The first was my pc at work.
