I found a bug today when using the PicLens feature. Using FireFox 3.6, simply view a gallery with PicLens. After the gallery loads click the X in the top right hand corner. The Gallery closes and you cannot scroll any more. If you click on the Gallery again in PicLens and then click to the far right or left hand of the screen (default close) you can then scroll again. This error should be a simply fix, but it is any annoying bug as most lamens go for the X rather than clicking off the the far sides.
Please let me know if there is a work around for this so I don't have to do a ton of code digging.
