Thank you for all the responses.
1) I am using Windows 7 (V. 6.1 Build 7601, Sp 1) and Internet Explorer 11.0.2.
2) I use cut/copy and paste exensively to edit Profiles and Profile message boxes with no problem.
3) My problem using cut/copy and paste involves ONLY the G2G Question/Answer/Comment pop-up window box. Here, the paste step does not work for me, either the ctl-V or the right click paste.
It is interesting that G2G box paste function works for others. This is good to know that am the only one with the problem, now I can adrress the issue as a local problem. I suspected this when saw the size of Ron's entry.
I also experience key stroke drops when I type into the G2G Q/A/R box (ONLY), elsewhere, I do not experience such drops. I have used Spy Bot and MalwareBytes to to scan and eliminate any viruses. And hardware diagnostics to verfiy my keyboard. No problems were found.
Thanks you all
Some progress has been made:
1. A test using the Windows 7 computer and Monzilla's Firefox browser does not demonstrate the copy/paste or keystroke drop problems described above that occur when in the G2G message box. Firefox also works normally with all other editing functions in WikiTree. (I do not use Chrome, so I did not verify Chrome's compatibility with the G2G message box.)
2. A test using a Windows 8.1 computer with Internet Explorer (IE-11.0) experiences the same copy/paste problem, but not the keystroke drop. This indicates an IE-11 related problem with the message box.
3. On the Windows 7 Computer, I removed IE-11 and installed IE-10 in its place. This solved both the copy/paste and the dropped key stroke issues...but, it introduces a new problem with the G2G message box; the carriage return (CR) does not work within the message box. This suggests an HTML problem associated with the WikiTree G2G message box.
4. I then, while in IE-10 with the message box open, hit the function (FN-12) key to bring up the HTML menu. Here, I chose "Browser Mode: IE-10 Compatibility View", and "Document Mode: IE-9 standards" for the message box. With this setting the copy/paste, keystroke drop, and the CarriageReturn problems went away. I would assume that, had I altered the Browser Mode and Document Mode options as above in IE-11, the problems would have been solved. This was not tested.
This suggests that the WikiTree message box is not up to Microsoft's IE-10/IE-11 standards. Other users should have similar problems, depending on browser and browser release level. Those using non MS browsers should not have issues.
The Wikitree G2G message box appears to require " compatability mode", which IE-11 seems to not be able to properly detect [http://answers.microsoft.com/en-us/ie/forum/all/is-internet-explorer-11-missing-compatibility-mode/e178b044-82ea-4c2d-aa52-c9d9867069b4],
and which competing browsers do. Also, IE-10 appears to have detection problems not present in competing browsers. For me the IE-9 document standards work.
Hope this information helps anyone else that has the problems discussed above. It should help the WikiTree Tech Support examine how WikiTree and it's G2G message box is programmed.
Note: Anyone removing IE-11 from Windows 7 should ensure that they separately remove the "IE-11 upgrade" from their computer in addition to deselecting IE-11 in the Control Panel, Programs and features screen. Otherwise one cannot install IE-10.
