Using FPV, I get disturbed by a small issue: the "Browse with Fast Picture Viewer" label in the context menu (Windows Explorer, Win7 x64) is not always in the same position. You can check the inconsistence between the left panel (folder panel) and the right one (file view).
I would like to be able to configure that (I know, it looks more like a Windows issue than a FPV one...), e.g. having the label always on the top.
