Well... I suppose that doesn't leave you with anything to do but put your two cents in the suggestions forum and hope Ruud comes around soon(or I suppose I could move this thread.) As far as I know, he hasn't been around since the launch of 4.61 earlier this year.
I haven't directly communicated with Ruud in like 7 or 8 years when there was a bug in KiXtart detecting DUN connections.
I took your advice however and included v4.53 and v4.61
