Browser Zoom about jquery.nicescroll

I'm working on it

show() is called in a couple of places in the onResize event, shown below:

if (!self.haswrapper&&!self.ispage) {        
    var vis = (self.win.css('display')!='none');
    if (!vis) {
      if (self.visibility) self.hide();
      return false;
    } else {
      self.show();
    }        
}

...

if (self.page.maxh==0) {
    self.hide();        
    self.scrollvaluemax = 0;
    self.scroll.y = 0;
    self.scrollratio = {x:0,y:0};
    self.cursorheight = 0;
    self.locked = true;
    self.setScrollTop(0);
    return false;
} 
else self.show();

The visibility variable set by show() and hide() seems to only be used as a short circuit to prevent showing a scrollbar that's already visible. I've repurposed this variable for my situation to indicate whether the user manually hid the scrollbar. Perhaps in the future there should be a check to see if the user manually hid the bar?

I found the bug!
When browser zoom is actived jquery returns strange floating values for innerWidth/innerHeight.
So I bypass jquery to fix this problem.
(you are right, visibility behavior needs a rewrite!)

Quick fix on 2.9.0 source code.

At line 869 change this code

  self.view = {
    w:(self.ispage) ? self.win.width() : self.win.innerWidth(),
    h:(self.ispage) ? self.win.height() : self.win.innerHeight()
  };

with this version

  self.view = {
    w:(self.ispage) ? self.win.width() : parseInt(self.win[0].clientWidth),
    h:(self.ispage) ? self.win.height() : parseInt(self.win[0].clientHeight)
  };

I think that's actually separate from what I was referring to. My situation is a little unusual in that I have overlapping divs where only one is visible at a time, so the problem is caused by having two separate nicescroll divs where only one should be visible at a time. When you change zoom onResize is triggered which overrides my manual hide of one of the nicescroll divs. I end up with the scrollbar from the invisible div being visible, so there's two scrollbars.

I had rewritten visibility routines.

Try DEV version:

Aha, I tested the dev version with my site and it works great. Thanks for
looking into this.
