disappearing ranges on closer zoom -!found cause, need help to fix!

[fallaha56]

Hi

First things first great software.

Sadly though when zooming in to timeframes approximately less than 12 hours ranges start disappearing from the timeline!

This is for a timeline with less than 400 ranges set into 5 groups.

For some reason the order of the group seems to affect when ranges disappear but this is not universal...

so...on further testing groupMinHeight option is the culprit -turn this off and all events display -but then empty groups become unreadable as they are crunched down...

any help?

Can it be that this has to do with clustering instead? Maybe the disappeared items are clustered wrongly?
