Windows XPP 9.3 (no X-Windows) same sequence the I3 window comes up while typing in the "search" but as soon as you press OK it returns E1r. 

Chris, can you then hit F11 and get into line editor(immediately after ok...before any other entry)?  That is what is weird for us...after ok when the first occurrence is selected in the Division, focus is in Er1...and F11 doesn't work until you reselect the division window.

Hi John,

Maybe this will help (excerpt from UNIX/Linux install guide):

Thanks Jonathan...somehow we missed this in our exceed setup.  That was the answer.

I believe we discovered after-the-fact (i.e. after the initial XPP 9.2.0 release), that with the change to the XyView/Sdedit GUI on the Linux platform from being Motif-based to GTK-based, that this additional (Exceed) X-Server setting change was necessary in order to get focus to properly go back to the main window.

Many here at SDL already had this X-Server setting cleared in their Exceed setup (didn't seem to matter to XPP with Motif-based GUI before the GUI change which way this setting was set), and so we hadn't initially noticed any focus problems.

The XPP 9.2 instunix.pdf document was hot-fixed in October 2017 on the docs.sdl.com web site (and the doc change was carried forward into the 9.3 version of this PDF).

That was the issue I didn't review the 9.3 settings for Exceed in the documentation.  We are jumping from 9.0 to 9.3 so at least it was explainable. Thanks much for the second set of eyes.
