PR# 12958 Editor tab fails to move or gets wrong cursor

Delete ~/.es directory.
Compile sample graphical application.
Type ctrl-T to create new Editor tab.
Left click on Editor tab APPLICATION and move it to right half of
   editor zone.
Left click on empty Editor tab and try to drag it into tab with
   APPLICATION.  Nothing happens (cursor doesn't change and empty Editor
   is not moved into same zone as APPLICATION editor).  Very confusing.
Try again.  This time it works - cursor changes and empty tab and
   APPLICATION Editor tab end up as tabs in the same zone.

Now repeat the following sequence several times:
1. Left-click on APPLICATION tab, move cursor down into area with text and
   quickly release mouse button.
2. Left-click on APPLICATION tab, move cursor down into area with text and
   quickly release mouse button.
3. Left-click on empty Editor tab, move cursor down into area for text and
   quickly release mouse button.

Soon the cursor stays the "Move Editor" cursor instead of the normal cursor,
even though a move of the empty Editor tab is not in progress.  Again,
very confusing.

In my opinion, this should go on the Critical list due to its high confusion
factor, though it won't affect us because we don't use the editor too much.

The first part of this report now seems to be fixed in 6.3.74123.
All items in report have now been addressed, so I'm closing it.

This is not completely fixed.  The part near the beginning that says:

   Left click on empty Editor tab and try to drag it into tab with
   APPLICATION. Nothing happens (cursor doesn't change and empty Editor
   is not moved into same zone as APPLICATION editor). Very confusing.

is not fixed.  The rest seems to be fixed.
Reopening report.

This bug is fixed in revision#68950.

Thanks for your report.
