Does xbmcgui.dialogprogress work?

[Ditchwater]

i can make progress dialog boxes appear no probs, but the bar indicating progress doesn't appear when i use the update() command. as far as i can tell, dialogprogess.update() only works on certain integers. 10 seems to work, for example, but it should work on all integers between 1 and 100, right?
am i doing something wrong, or is it busted?

cheers

ps: sorry for the cross post. i posted this to the wrong forum at first.

if, for any reason, your update integer is nul, it hides the progress bar
