The icons popping out of Fences part of this is not a new problem, as I reported it twice to support long ago with version 1 Pro. The slightest misstep with an icon in a Fence is apt to send it out, first by moving it out of line with the others. In fact, I often don't know that anything happened until later when I need to do something in that Fence and notice two icons on top of each other, or unexpected and apparently illogical things start to happen. I learned long ago that the first thing to check is the alignment of icons. Fences is very fickle and not well set up to snap icons that are slightly disaplaced within the borders of a fence back into line.
Last night, with Fences 2, I also got the invisible icons problem. Clicked on the right edge of my desktop by accident, not sure whether in or just outside of a fence, and three icons in a vertical row of six disappeared off the right side of the screen. And not just them, but four in a vertical row of eight on the left edge of the monitor also disappeared. Had to reboot the computer to get everything back to normal.
Writing to customer support is frustrating, and is hit and miss in terms of results. It takes days for staff to respond to anything, and often it requires a few emails back and forth to clarify all your meanings. By then, two weeks or more can have passed. Even my report last week about the missing "Exclude this icon from Fences' quick-hide," an absolutely essential bug that should have been fixed right off - it's been a month already - took six days to get a reply. And what did six days get me (us)? That my email was being forwarded to the appropriate department "for their review and recommendations." Review and recommendations??? How about for a fix!
