I encounter problem with very slow(delays) showing new image in stack when scrolling in Chrome(Firefox works nice). The weird part it is that when I added \"overflow: scroll\" to div in which is canvas, scrolling images was was working ok, with no delays. Another weird thing was when scroll delay occured when I clicked left mouse button image showed in instant. I think the problem is with mouseWheelEvent. Could it be that Chrome first call native browser event to scroll whole page and the second is event for scroll image?? Could you look into it, because I don't know if it cornerstoneTools bug or just my component unsual behaviour. I attached library with quick fix after some investigation I done in code.\r\n \r\n[cornerstoneTools_with_fix.zip](https://github.com/chafey/cornerstoneTools/files/544121/cornerstoneTools_with_fix.zip)\r\n\r\n"}}
