Using jan17 commercial trunk, win98 Have seen this just over the past few days... All of a sudden (haven't figured out if there's a specific trigger) single selections/clicking in thread pane will cause a visual effect of having multiple selections, the highlighting from previous selections will stay. Although the appearance is that multiple messages are selected, only the last message selected receives applied commands (such as delete, label, etc.). Vague steps: 1. Open a folder with lots of messages, select a message in the thread pane. 2. Click to select another (single selection, not a Shift or Ctrl click for multiple selections) message in the thread pane. Repeat many times. Result: at some point you'll see multiple messages highlighted, the highlight of previously selected message(s) will stay although only the last message selected is really selected for any command purposes. Expected: only one/single message highlighted.
Pardon if this is a duplicate -- couldn't find one...
I keep eyes opened on any machine. So far, not seen.
