I can confirm the described behavior on my Windows 98 machine. But the 
problem seems to go deeper. If I put a Button on a Form, and double 
click the Button to let the IDE write the OnClick method, I get the 
error message:

"The component editor of class 'TDefaultComponentEditor' has created the 
error: 'Unable to find method. Please fix the error shown in the message 
window'."

The class TForm1 is mixed then. See attached screen shot.

Regards, Bernd.

Sorry. My fault. I fixed that an hour ago in svn r19726.

I have attached a patch with a few debugln in it. I don't know if they 
will show anything useful, since I have no idea what is going on.
If you apply it, you need to start lazarus with a logfile, to capture 
the output. (There is a command line switch, but I have to find it 
myself / I usually compile as none "window app", which means my Lazarus 
runs with a console-window showing all the output)

Also if you do this, test it with only one Synedit open. (You can 
compile a standalone app, with one SynEdit, and set the font from inside 
the app)

I applied the changes in sysnedit.pp and syneditextdrawer.pp
then did a make clean all

This happens when I build and start my test app.

In OI the font is set to Verdanana, size -12 (height 16), pitch fpFixed

F:\LazarusProjecten>test
SetStyle created font for idx=0 name=default handle=596
SetBasefont name=default  basefont.name=default Handle=596

What was your latest revision that seemed to be OK?
(My latest was 18956, I hope yours is later...)
That would help us finding where things went wrong.

File region locking under Linux

I have a problem with file region locking under Linux.
First I start setup to create a file and writelock range 10..30
--------------------------------------------------------------
program setup;

{$mode delphi}{$H+}

Uses    cthreads, Classes, SysUtils, BaseUnix;

Const   Fn      = '/home/anthony/test_lock';
        F_RDLCK = 0;
        F_WRLCK = 1;
        F_UNLCK = 2;

Var     F, I    : Integer;
        Region  : FLock;

Begin
   If FileExists (Fn) Then DeleteFile (Fn);
   F := FpOpen (Fn, O_RDWR Or O_CREAT, $1B6);                   // $1B6 
= o666
   For I := 0 To 255 Do FpWrite (F, I, 1);                      // 
Populate file
   With Region Do                                               // Set 
WriteLock 10..30
   Begin
      l_type  := F_WRLCK; l_whence := SEEK_SET;
      l_start := 10;      l_len    := 20
   End;
   If FpFcntl (F, F_SETLK, Region) = -1 Then

Does that test app use a syntax highlighter? From the output I would 
guess that it does not. (because the font is only recalculated in plain, 
but not in bold or italic / You "compare app with memo" in your 2nd mail 
shows  plain style only.)
Anyway, as long as it doesn't, the output looks good.

One thing I noted in the pictures of your first mail (highlighted pascal 
before/after): In the after text the output of the bold text seems to 
use a different font than plain text. Compare the "u". The plain "u" 
(and any u in the before pic) has serif/serif-like extensions. the bold 
"u" in the after pic, has not.

Wrong list. This question is better asked on the FPC mailing list.
