Spark 2.5.6 Bug: Menus only appear on primary monitor

If you run a multiple monitor setup, when you click any of the menus in 2.5.6 they appear on the closest edge to your secondary monitor instead of on the monitor. I haven’t observed this behaviour in any previous versions and everyone in our office is running dual monitors, therefore this stops us from using 2.5.6.

A bit further investigation showed that the previous version wasn’t removed properly during the install of 2.5.6. I removed all version and re-installed and it works fine now.
