(5) Another attempt to fix all known issues is my a new patch Fl_Counter_v2.patch (attached). It's likely not the final solution (fixing symptoms only) but it's a start.

Rob, can you please:

(a) test and (hopefully) confirm that this patch fixes your issue too?

I tried this patch (thanks for the prompt work).  It helps, but isn't a fix...

When I click the counter, it now increments two values (usually) and then stops.  It doesn't skip from 2 to 4, I see the intermediate 3.  It goes 2, 3, 4 and then stops -- for a single click.

Occasionally (once out of 20+ attempts) it will only increment by one (my sequence switched from even to odd).

In my demo I need to hold the mouse button for a "significant" time. This time is presumably longer than 0.1 sec which is the repeat timer of Fl_Counter. This can be seen clearly in the existing code: if the FL_RELEASE event is delivered before the timer event the internal variable `mouseobj` is reset and the timer repetition is terminated.

Is it possible that your mouse button "click" lasts longer than 0.1 sec?

I am just clicking the mouse in a normal way.  I am not dwelling on the button in any way.  I don't have a millisecond stopwatch connected to my mouse finger -- but I'm not doing anything unusual as a user. 

Is a counter supposed to repeat events if you hold down the button?  I guess I'm failing to see how it doesn't behave like a normal button press and why we don't see this problem for all kinds of FLTK events.

If it is 'supposed' to repeat, then I should probably avoid Fl_Counter in the first place and just use normal buttons.
