Okay so iv asked a few of my mates running windows 7 to see if this strange behaviour appears on thier PC's runnining windows 7, and indeed it does.
The bug iv noticed is basically when closing a specific window the 'windows explorer' icon on the taskbar flashes with a box around it and then suddently dissappears. (When windows explorer is not an open applcation). The illuminated box is only ment to appear if the windows explorer icon is open.
Step to step guide to replicate the 'bug'.
1. Make sure all windows are closed, especially 'windows explorer' folder.
2. Open network and sharing center
3. Navigate to where the text apepars 'Connections:' and click on the link right next to that. Its either Wireless Network connection/Local Area Connection.
4. Once you see the connection status window appear, containing details of the the duration, speed etc...Observe the 'windows explorer' icon on the taskbar and proceed to close the connection status window you have open.
Did you see the 'windows explorer' icon flash briefly with a box around it?
Is this normal behaviour? This doesnt seem to happen when other applications are closed down... Is this a bug!?
