Why is term recognition not working consistently?

Since upgrading to Studio/MultiTerm 2017, we have noticed some problems with integration. In the most prevalent instance, terms are not delivered immediately to the Term Recognition window automatically when moving to the next translation unit. The window is simply blank with "No terms found" or whatever. Simply cursoring in and out of the TU is usually enough to get the system to "wake up" and fill in the Term Recognition window properly again.

Nevertheless, this is very frustrating, especially since this was never a problem with TS/MD 2015.

When will this be fixed?
