It certainly is. A pervious version of GEM++ used the ED_START objc_edit
operation. GEM ignores this operation, and it is documented as Do Not Use.
LTMF crashes if it is used. It's hard to say which is at fault, in this
case - but it doesn't matter, because GEM++ doesn't do it anymore. Simply
turn off the extended editor, and it works fine. What can I say - I don't
use LTMF and I didn't see the Do Not Use until more recently.

Including Falcons in 256 colours and in TrueColour? Use offscreen bitmaps
in those resolutions and you are talking major expense (640x480 - a small
offscreen bitmap - is almost a megabyte in Falcon HiColour).
I'm not totally adverse to offscreen bitmaps. Just be extremely careful
about when to use them. Don't just use them because it is easier.

Point-to-type: TOSWIN, UW.
Exit highlighting: Menu items (since day one)

Depends on the highlighting, probably. Motif uses an outline as the highlight.
I don't really like it either, except for menus.

Not true. Rectangle events are provided to the application EVEN WHILE
THE MENUS ARE BEING USED. Strange, but true. (I can see it is going
to cause be problems, as the drop-down menus don't clip the rectangle
lists!)

Only the name for these options needs to be standardized - just so that
anyone who DOES want to provide them knows of a defined way to allow the
user to disable it.

Hehe... it's the old story. A War to End All Wars. The Folder to End all
Folders. Alas, a Geneva user would look pretty silly creating a C:\MULTITOS
folder.
A C:\SYSTEM or C:\SYS folder is the best we can do. Recommend putting
C:\CPX and C:\GEMSYS and C:\SPEEDO there and re-directing the
appropriate pointers.
