SB 5.33.1. Win 10 Pro. Chrome fully up-to-date.
I use a very reliable third-party bookmarks program called miTaggedMarks (mTM).
mTM has co-existed with SB since at least 09 Feb 2017 (the date of my oldest mTM installation EXE).
Recently, when I close mTM, any bookmarks inserted during an SB session are not saved. There are no error messages.
However, I'm given the option to save any test downloads within SB during that session - such as PDFs.
If I now run mTM non-SB, insert some bookmarks and close mTM, these new bookmarks are saved correctly.
IMHO, that proves the fault lies with SB.
Further info: When I insert a bookmark in the sandboxed mTM, I can see the entry here:
C:\Sandbox\<username>\DefaultBox\user\current\AppData\Roaming\miTaggedMarks\<variousDataFiles>
The date and time are correct.
I would be grateful for any advice that allows me to use mTM within SB.
Thanks.
