[pardon if this comes through twice; local software here said it choked]

About a month ago I decided to finally stop being bothered by various
behaviours of some applications and patch out the offending code.  This dealt
primarily with cursor settings and font usage.

I'm sharing these patches in case some other people might have encountered
the same reaction.  I don't believe there is any possible harm to the
applications involved, but do this at your own risk, please, on a backup copy.
I've used them patched for some time now and have had no problems.  If you
don't know how to apply the patches but want to, try to ask for help--it's a
potentially risky business.  E-mail inquiries welcome.

Changing my default Application Font (to Chicago) prompted several of these
patches; I find it interesting to see which applications use appFont or
geneva explicitly.  

Note to developers: if you have any cases of using appFont size 9, please
change them unless there is a very good (and specific) reason.  I believe
most of these are mere oversights and don't come up often since the
prevailing appFont is Geneva.  As soon as you set it to something that
doesn't have a nice 9-point version (like no 9-point version) it looks
horrible.  The culprits here range all over, including Apple (Calculator DA)
to SuperMac (DiskFit), both producers of high-quality software in my opinion.

Fedit hides the cursor when it first starts up and finally shows it again a
few seconds later after it is done reading in all its tons of DITLs.  This
really bugged me.  This patch is easy:

  A8 52 4E BA	[HideCursor() and something else unrelated]
   | |
=>4E 71		[NOP out the HideCursor().  Note: this should not be a problem
		 with ShowCursor() balancing since he calls InitCursor() next]

***
MacScheme changes the cursor to all different things depending if it is over
the title bar, horizontal scroll bar, vertical scroll bar, or grow icon.  I
feel this is against the Interface Guidelines, and it bugged me.  The fix:

  486D F5F4 A851 4EFA 00BE 486D F6C0 A851	[bunch of SetCursors()...]
   ||   ||   ||		    ||   ||   ||
=>4E71 4E71 A850	   4E71 4E71 A850	[to NOP's and InitCursor()'s]

  486D F67C A851 4EFA 0004
   ||   ||   ||					[same...]
  4E71 4E71 A850

6600 000C 486D F638 A851
	   ||   ||   ||
	  4E71 4E71 A850

***
DiskFit

I like Geneva 9 for the display of disks and so forth, NOT Chicago (or
whatever else that doesn't come in 9) 9.

This patch must be applied THREE times (in different places):

  3F3C 0001 A887 3F3C 0009	[SetFont(appFont) and FontSize(9)]
 	||
       0003			[ to SetFont(geneva) ]

***
Calculator DA (Apple one)

Same Chicago (...) 9 problem.

  A873 3F38 0984 A887
	||   ||
       3F3C 0001

***

Actually, if you're brave and smart, you can probably use the

  3F3C 0001 A887 3F3C 0009	[SetFont(appFont) and FontSize(9)]
 	||
       0003			[ to SetFont(geneva) ]

patch on most things that use appFont with 9 point, but no guarantees!

Enjoy, if you like this!
