Progressive lag between mouse click and popup appearance

[mchiapello]

Hi, I noticed that after the second set scout ovscout2 becomes very slow. There is a progressive lag between the mouse click and the popup appearance.

Is there something I can do?

We haven't noticed this behavior, so I'll watch for it next time I am scouting a match. The lag here will be more noticeable with a less powerful computer (we should see if we can optimize the reactive flow to make this faster) but I am not sure why it would get worse as you scout more of the match.

Is there something that I can do to diminish the lag effect in your opinion?

@mchiapello I just pushed a small change to the dev branch (https://github.com/openvolley/ovscout2/commit/35da660b0423fff44542935c7a34de7d54a3006c) that prioritizes the handling of click events. Would you mind testing when it's convenient and see if it made any difference? It seems to help on my machine ...
