Constant refresh of source drive

[liamtoh1]

I get this problem only when I mount an ISO and want to create mkv file.

Here are my steps.
1. Mount the ISO
2. Start MakeMKV and choose the virtual drive
3. Go to "File", then "Open Disc" or alternately, click on the "Open Blu-ray disc" picture.
4. Once it parses the disc, it open the various folders of the ISO file aka Virtual drive.
5. In a few seconds, the software will quickly go back to home screen of the MakeMKV software. It gives very little time to select / de-select your files and click on "Make MKV" button.

Here is the video of the issue (no audio).

6. If I get lucky/quick enough to click on "Make MKV" button, the mkv file is created correctly without any refresh back to initial screen.

Can some one help?

You should not have to MOUNT an ISO, just open it as a file.

I think this works. Thanks a lot.
