The page scrollbar on the right of my internet browser disappears after you view the gallery. So, (try this please to understand the problem) go to my blog bertholdbouman.wordpress.com, click on one of the tiles of the photo gallery of the first article, the photo viewer (the one that is projected over the actual page, with the black background, and the < > to browse through the gallery) is opened, but when you close it again with the X on the left top, the page scrollbar of the internet browser then disappears.
Mouse wheel scrolling doesn't work anymore either, only refreshing the page cures the problem.
Happens with all current browsers, IE8 and 9, Chrome (Version 24.0.1312.52 = latest one) and Firefox 17.01 and 18.0, the latter is also the latest available version. And happens with XP, Vista and Win 7, but the OS is imo not the problem.
As this concerns ALL wordpress blogs and all themes it would be appreciated if someone from WordPress can react on his?
This has been going on for at least 24 hrs now and no one from WordPress has given a reaction. Are you aware of the problem?
The blog I need help with is bertholdbouman.wordpress.com.
