I noticed that when i select a message, or multiple messages, the task icons (move to folder, toggle unread etc) are on the far right. They cover the vertical scroll bar. There is no way to select it. I have to click the below those icons and press and hold until the tab moves low enough for me to be able to select it and drag it more. Not much of a problem if i have few messages in the folder, but if i have thousands, it will be a long time before the slider gets low enough for me to click it and then drag it the rest of the way down.
I included a screen shot with a red arrow pointing to what i mean. I cannot click where the red arrow is and drag the slider down.
