Hi Travis, I think you've encountered the same problem I just finally 
solved yesterday. On Windows gdal_merge needs to be CALL'd else the 
control doesn't return to the original batch file:

@echo off
:: My_Merge.bat
CALL gdal_merge.bat -o out_1.tif -of GTiff in_1.tif in_2.tif in_3.tif
CALL gdal_merge.bat -o out_2.tif -of GTiff in_3.tif in_4.tif in_5.tif
echo --- Done!


cheers,
