Memory issue

Apologies if this has been addressed before - I searched for my issue in previous threads, but hadn't seen the specific problem I'm having anywhere. I'm trying to open a fairly large file (3 GB) which is a Z series over time with multiple stage locations totaling about 2800 images. I've opened these routinely on a mac mini running both 10.6.8 and 10.7, with the computer having 8 GB of RAM. Generally, they open in about 10 minutes.

Right now I'm working at home on a 64 bit Windows 7 machine with an intel i7 3.4 GHz processor with 16 GB of RAM on a 64 bit version of FIJI, so I would expect the files to open even faster, however this isn't happening. I haven't gotten one to open at all yet, and I've been waiting over an hour. I checked the memory and threads, and it's set to use 12000 MB of memory (so the 75% of the total memory that was recommended on the FIJI wiki) with 8 threads and the "Run garbage collector on status bar" box is checked. I have tried using less threads and less memory, but the results don't change. I am monitoring the computer's performance, and the CPU usage shifts between 12% and 15% while the memory usage is between 4.00 and 4.7 GB, generally with at least 8GB "free."

Is there something I'm overlooking about changing the memory allocation? FIJI seems to ignore whatever I set.

Thanks,
