When one XTREE has the focus, and you click on a cell in another XTREE, the XTR'TARGETROW/COL was failing to identify the cell clicked on if the original XTREE was not in cell editing mode at the time. This would occur if there was an intermediate click on something else, that terminated the original cell editing operation without causing the first XTREE to exit.
Note that in such a situation, the only way to identify which XTREE was clicked is by the EXITCODE. If you terminate the one XTREE session by clicking on an inactive XTREE, the returned EXITCODE will be the overall exitcode for the inactive XTREE (as set by it's XTR'KBSTR value).
The sample program XTRA10 - 1.0(2) has been updated to better illustrate the ability to click between two editable XTREEs.
