Not opening last version of a synchronized file

I regularly notice following behavior when synchronizing files with client-server software, especially with .txt files. > 1. Mac computers A and B contain an up-to-date version N of a file file.txt. > 2. I edit the file on computer A, then synchronize its version N+1 with the server. > 3. I synchronize computer B with the server, so version N+1 of the file is downloaded. > 4. I open file.txt on computer B (using Command–Space bar to locate the file in Spotlight). However, it opens the version N of the file before synchronization. > 5. Closing this file and repeating step 4 now opens the correct version N+1 of the file. The problem with this is that if you do not notice at step 4 that you're not seeing the last version of the file and start modifying, you create a conflict. Is this behavior caused by Mac (Finder/TextEdit)? How to avoid it?
