I forget where I found it but if you have trouble I can see if I can find it again. BTW: gnu-win32 is a mail list. Anything mailed to gnu-win32 gets copied to anyone on the list. - \\||// ---o0O0--Earnie--0O0o---- -earnie_boyd AT hotmail DOT com- ------ooo0O--O0ooo------- >From: Mark Johnson >To: "'Martyn J.
