I have been using the latest version of the program (1.1.14.0) on Windows 7 (64 bit) running 4 GB RAM. I have noticed an unusually high memory usage on my PC as seen in the attached screenshot.
Mostly tends to happen when I leave the PC locked for a long time / multiple users use the PC (multiple accounts).
Secondly: what kind of fix were you expecting?
This issue could be taken into account when programming the next version of the program.
Fixing the issue on your machine long-distance, however, is very different…
