Could anyone please mail me with any answers to the following problems?
We are in the midst of moving from SunView to XView, and we have hit
some snags:

1. In SunView, we wrote event procedures so that the buttons in a panel would
   invert when the user moved the cursor over them. In XView this seems
   impossible to do...  We can't seem to get LOC_MOVE events in a Panel...

2. We have to quickly convert some SunView code to XView that involves
   the use of pop-up menus. Since XView does not block on menu_show, what
   is the quick-and-dirtiest way to simulate blocking menus to get this
   thing up and running. (Unfortunately, it looks like a real bear to tear
   the code up into action procedures.)

3. In Open Windows 1.0, we have been unable to eliminate the frame menu.
   The frame menu is now under the control of the window manager, so how
   (short of NO_DECORATIONS, since we want a window title) can we get
   rid of the menu or modify it?

(In case anyone is wondering, item #1 involves a scrollable panel of 250
buttons. As things of interest happen, the buttons appear, and the user
can pick the button to get more details. This simulates a two-dimensional
Choice List. The users are very paranoid about hitting the wrong button,
hence the desired feedback.

Actually, I am a little suspicious, since a standard pin-up menu does not
provide feedback when it is pinned up, so maybe XView doesn't pass on MOVE
events anymore--just DRAG events?

And maybe Sun could add two-dimensional Choice Lists to panels, please?
(Items are added across rows first, wrapping to new rows as required.)

Item #3 arises because our users' management is very paranoid, and wants all
the windows to be tiled, with no chance of windows getting lost behind other
windows, etc.)
