>>>View all checked items button doesn't work in the search result. If I check some or all items in the message search result and click 'View all checked items' than search results disappear and that's all. The checked messages aren't displayed.

>It still doesn't work properly. For example, do search on 'ShellExecute parameters', check all items and click View. It would display only 5 messages. Now uncheck all, check result #5 (NO column) and click View. The message popups "You need to check at least one item".

I don't have those behaviors here. I checked as you said all items and I got them all. Then, I checked only item #5 and got only that one.
