+PAINING & PERFORMANCE
+
+* Too much painting 1 (Edwin 3/11/2006): when i click in the workarea (to put
+ the cursor in another part of the text) the screen is repainted *twice*
+ whereas it seems to me that no repainting is necessary at all.
+
+* Too much painting 2 (Edwin 3/11/2006): There is also a lot of painting going
+ on when selecting text. When selecting a word the whole screen is repainted.
+
+* Too much painting 3 (Edwin 3/11/2006): the screen is repainted even when the
+ selection does not change (moving the mouse with the left button pushed down
+ always triggers a repaint).
+
+* Cursor is still not visible on MAC (Bennett 3/11/06).
+
+* Slowness on MAC 1 (Bennett 3/11/06):
+ There seems to be a fraction of a second lag between when I press a key and
+ when the letter appears on screen -- but the time lag doesn't obviously vary
+ with the amount of text on the screen (as was the case previously). Right now,
+ the speed of normal text entry makes LyX-1.5 usable on my
+ not-fast-but-still-not-outdated computer. (Not sure how it would be on my
+ slow-but-still-usable laptop.)
+
+* Slowness on MAC 2 (Bennett 3/11/06):
+ Speed is still an issue typing in insets: noticeable lag between typing and
+ text appearing on screen. This does not seem to be compounded by having nested
+ insets, and it seems to be compounded only a little by the amount of text in
+ the inset. (This is especially a problem in math environments.)
+
+* Slowness on MAC 3 (Bennett 3/11/06): Some operations that with 1.4 are
+ pretty much instantaneous (inserting a footnote, dragging the mouse, switching
+ to LyX from another application, opening dialogs, etc.) take quite a long time
+ to complete in 1.5.
+
+
+MAC OS X
+
+* Cursor is still not visible on MAC Bennett (3/11/06).
+
+* Drawing oddities on MAC (Bennett 3/11/06):
+ Lines occasionally overlapping vertically, math characters not properly
+ aligned vertically.
+
+* Many issues with toolbars on MAC (Bennett 3/11/06):
+ Most obvious of which are that icons are spaced too widely and that changes in
+ the visibility of the toolbars with the GUI do not stick after the screen is
+ redrawn).
+
+* Many issue with dialogs on MAC (Bennett 3/11/06):
+ Most obviously: the Preferences dialog -- which can only be accessed now via
+ keyboard command, not from the menu -- appears initially too small and must be
+ resized; not possible to select buttons with the keyboard).
+
+* Some oddities with View menu on MAC (Bennett 3/11/06): DVI does not appear
+ in the menu, even though a converter and viewer are defined in Preferences.
+
+* Menu bar disappears on MAC (instead of being disabled) when dialogs appear.
+
+* Mac Crash (Bennett 3/11/06):
+ On launch from GUI (by double-clicking on the LyX icon). As I reported before,
+ this happens only when using the GUI; I can successfully start LyX from the
+ Terminal, with or without gdb. Hence the only debug information I get is this,
+ printed out in Console.app when I try launching from the GUI (note that the
+ number changes everytime):
+
+ Wrong command line option `-psn_0_182321153'. Exiting.
+
+Hint from Andreas Vox: LyX must accept any option starting with '-psn' and
+pass it oon to the Qt initialisation. On Mac this gives the app a link to the
+Window system.
+
+* Mac Crash On quit (Bennett).
