ASCII import "not responding"

Hi Mike,
I'm running GM v15.1.3[64 bit]. I have 2 questions as I suspect they are related to the problem I am having.
I am trying to import an xyz.csv as "Elevation Grid from 3D Point Data", GM runs "Loading ASCII Text File" and then "Gridding 3D Point Data" but pauses at 50% and stops responding. This happened all day Friday and then for some reason it worked yesterday! So I added it to my gmw file and all worked.
Today however I cannot open my gmw file as GM stops responding as soon as "Gridding 3D Point Data" reaches 50%.
The csv file is in excel and it has 1mill+ lines so I suspect the csv file is causing this.
The question(s) is there a way around opening the file to stop the "not responding" issue & I have reached the maximum number of lines in the excel file but have more data to add. Is there another software option to replace excel or is there some way to use multiple csv excel files and then combine the 3D data so that it displays as if I was importing the entire file as one, as it is important for the final image.
I've rambled on a bit Mike, I hope I have made it clear enough.
Many Thanks Phil.

Phil,
At 50% the process goes from triangulating the points to sampling the TIN to a regular grid. Are there perhaps some points far off in the distance that are resulting in a very large grid when really all of the data is concentrated in one area? If you load the data as a Lidar Point Cloud rather than directly gridding do they all come in fast? Then can you grid that?
Also I would suggest getting the latest build (v15.1.9, but not yet released officially). I have placed a new build at http://www.bluemarblegeo.com/downloads/global-mapper/global_mapper15.zip with the latest changes for you to try. Simply download that file and extract the contents into your existing v15.xx installation folder to give it a try. If you are using the 64-bit v15 version there is a new build at http://www.bluemarblegeo.com/downloads/global-mapper/global_mapper15_64bit.zip .
Thanks,
Mike
