I have this problem with AE. I have used the dependencies menu to collect the files I only need for that project and upon saving the file, it opens immediately and closing my main AE Project, which I still need to export the other compositions individually. How can I disable the opening of the AEP file automatically after collecting the the dependencies because I still have other compositions to export?
Your help is greatly appreciated.
Nobody can tell you anything without proper system info or other technical details like exact version of AE or what's involved in the project.
After Effects has always opened the project file folder that is created after you collect files. This is standard behavior. The new collected file should not open unless you click the file name in the revealed folder.
What are your collect settings? A screenshot may reveal problems. I can't seem to replicate your behavior.
Complete build number of AE and your system info may also lead to some clues.
