That's good to know. Now we have confirmed that the latest version of the plugin still exhibits the problem.
Meanwhile, I have confirmed that there is no known work-around for the problem at hand. Now we can escalate things.
It appears to be a genuine bug that you've found with the plugin, and the author of the plugin says: "If you have contacted support and established that your problem is definitely a bug then you can raise an issue on the project's github site."
By support, the author means addressing the problem over at the [stackoverflow site, or over at the [url="http://groups.google.com/group/jscrollpane/"]jscrollpane google group](http://stackoverflow.com/) page.
Once the people more familiar with jscrollpane have gone through the issue with you there, and the bug is still confirmed to exist, it can be raised as an issue on the official jscrollpane issues repository.
For future reference, the full details about this are at the jscrollpane's support section of their site.
