Slow reaction time or not registering double clicks

Slow reaction time or not registering double clicks

Hi,
sometimes Bigin doesn't seem to react to clicks immediately.
This is most noticeable when you try to open a company or contact record by double clicking

You click and click and click and click and nothing happens. Refresh the site and then maybe it works again.
The most confusing thing is that it seems to be different depending on which record you are trying to open.
Some open right away others do not.
Just to be clear, this is not always the case but often enough to notice.  (This has nothing to do with our internet speed, since we have over 500 mbit/s. Also, we are on a European server.)
