First, THANK YOU for that beta upgrade!!! It fixed my issues to date beautifully!
As to the issue at hand - i have autohide turned on (meaning that i have not tested this issue with autohide turned off). When i hover over an item (button?) in the taskbar i have to click it immediately in certain cases. These cases are as follows: Though the normal behavior is once hovering over an icon a descriptive text will shortly show up just beneath the icon, in some cases the text appears overlaying the icon and at that point the icon can no longer be clicked. A case in point is the magnifying search glass that is adjacent to the main menu icon/button; example follows:
Directly underneath where the above shows "Search" is the magnifying glass and cannot be clicked upon until one moves away from the area, the taskbar is restored to original appearance, then going back to the magnifying glass and quickly selecting it. Though i can't recall which other instances with which i ran into this issue, i know that they do exist.
I hope i have not been overly "descriptive", just trying to eliminate "presumed knowledge" that would require a visit to the California Psychic Hotline to know what i was trying to say...
