Is that the entire story ? I tried this with yesterday's patched version (windows xp) and found:

 > list.files(getwd(),"*.txt",full=T)
Error in list.files(path, pattern, all.files, full.names, recursive) :

         invalid 'pattern' regular expression

 > list.files(getwd(),'.txt',full=T)
[1] "C:/Documents and Settings/suresh/BDE_SysInfo.txt" [2] "C:/Documents and Settings/suresh/dxva_sig.txt"

Replacing "*.txt" with '*.txt' seems to do "something".

-s.
