As I mentioned here; http://newsgroup.xnview.com/viewtopic.p ... =15#p83230
There are the same two bugs quoted from myself:
For bug '1.' is not a feature request because I have seen 'normal' transparent PNG images display transparency on the tab's previewbudz45 wrote:1. It would be nice if in a future version you supported it's transparency on the tab preview; http://i39.tinypic.com/x3rxi.png
2. BUG: There is a visual artefact (faint grid lines) which needs resolving when zooming in/out of this picture; http://i42.tinypic.com/sfdw1d.png To reproduce, all you need to do is zoom in and out of the picture to see the artefact. I will make a new topic about this in 'MP Bug reports' forum
