I am running XP Professional SP2 with 1 GB RAM on a Dell Inspiron 9100
laptop.  Most of my computer work is related to my photography profession.  
Naming files & copying/moving them in Windows Explorer is a major, required
part of my work.  However, recently when I try to copy/move a file from one
folder to another, the program freezes & an error message indicates that
Windows Explorer has encountered a problem & must shut down.  

In addition, I frequently get a message that a filename is invalid or too
long, even though I have been using/copying filenames equal or longer (e.g.,
30+ characters) for the past two years.  Reducing the filename to a small
number of characters (e.g., a dozen or less), & including a small number of
files at one time, does allow the above procedures to be completed without a
freeze.

With regard to possible malicious invasions, I regularly use programs for
detecting viruses, CA’s pest control, Microsoft’s “Malicious Software Removal
Tool”, spam, ad-ware, etc.

Please advise!

Thanks you,

Richard Evans
