MT-ETCBC.syntax scrolling eratic

[Iconoclaste]

When scrolling through the parallel pane that has the MT-ETCBC.syntax module open, the pane regularly skips one or two verses backwards or forwards when the dividing line between verses touches the top of the pane. It is very frustrating since it is necessary with larger verses to scroll within a verse in the syntax module, but doing so regularly takes me away from the verse I was looking at because I unknowingly reach the top dividing line of the verse. This glitch affects the verse boundary in both directions, whether scrolling upwards to touch the dividing line or downwards to touch the one below it.

 

I would post a pic, but at this point it is better just to record my screen. 

 

I have not tried this with the other syntax modules, because this is the only one that I have currently.
