Based on email from Patric, looked for "_mm" and "._mm" files in account, couldn't find any. Tested Contribute 3 in Win XP Pro on computer in mac lab. Created new connection, then used it to edit and publish a file. Got same problem with group write setting that I had using Contribute 4 on Mac. Mentioned it to Mary S. who said she had successfully edited php with Contribute in Windows somehow, but doesn't remember the details. Reported back to Patric in ESG
