ICONs disappearing

[DevOma]

Ok, I think I found the bug - an Caching issue - did you activate automatic refresh (Application settings) - because in my tests only a refresh of the treeview cleared all icons in the cache and after that they won't be loaded anymore...

If nobody goes to the Settings and save them the icons should be there after a program restart - but if you press OK in the Settings dialog you will save the cleared icons list...
