Perhaps. But why it doesn't happen in other cases. I can scroll up and down any page here (except the case I mentioned above) and there is no such effect.
Here is HTML code of the element in question:
<iframe style="margin-bottom: 1em; margin-top: 1em; border: 1px solid #CCCCCC;" align="CENTER" width="95%" height="200" scrolling="auto" src="/forum/r27564935-Vertical-scrolling-with-latest-Chromium-while-editing-posts;iframe=1#27568527"><center>(there should be an inline frame here)</center></iframe>
Could it be iframe
style problem? Again, I don't see this effect in any other places... Only here.--
Keep it simple, it'll become complex by itself...
