I just commited changes to a file (bringing it to revision 1.3). I then updated the file and to my surprise I got back revision 1.2 (how the file looked before my commit).

Checking the history if the file shows that there is a revision 1.3 (most recent) and a 1.2 before that (which is identical to my local copy).

Ive tried removing the file and updating the folder, causing the file to be downloaded again. Ive also tried fetching a clean copy of the file of HEAD.

Clearing cache and fetching HEAD doesnt work. But forcing an update to revision 1.3 explicitly does. But doing a normal update after that causes it to go back to revision 1.2.

This is on a Windows XP machine, server is also a Windows box. Im using TortoiseCVS.

Does anyone know what could be causing this?

(If you dont know how to fix it, I will award bonus points to anyone that can tell me why CVS broke and, hopefully, how horrible it will be to fix it. I want to add it to my list so that maybe some day I can convince my colleagues to finally give it up in favor of a more modern VCS.)
