[Plugin: NextGEN Gallery] thumbnail display intermitently incorrect

Salutations,

Having an issue with the thumbnail display that appears to be intermittent, and I can’t seem to figure out what is causing it. You can see an example of it at the bottom of this page…

As you can see, one of the rows of thumbnails is incorrectly paginated – or skipping a beat. There are no thumbnails missing – but there is a place for something – I don’t know what – leaving the first three photos below the 4th.

I have checked to insure that all of the photos are the exact same size – and I even add dead space to the photos to insure it.

The thumbnails are fixed via the options pages, and the pagination is set at 20 – which is usually fine.

Like I said – this is an intermittent problem, and I don’t know how I can correct something I cannot duplicate. Is anybody else having this kind of problem?

Any / all help will be appreciated.

Best Regards

Mike
