Very Slow Page Load and Form Buffer Error

For some reason WebExplorer Free takes several minutes to get the directory to first come up.  I suspect the problem is related to a duplicate form buffer error message that comes up when trying to save the file(even without making changes to it)??

Calculation of total size of huge folders may take long time.
You can comment out the lines that calculates total sizes. Search
".size" in the script and comment out the related code.
