Hi everybody! Since some of you told me that I should post info about discovered system bugs (after confirmation from Apple), there is the second one (the first was about OpenATPSocket): Form my mail to Apple: >............ >Second: It seems to me that I've detected a bug in the List Manager. If you >perform LAddRow operation with the list which resides in an inactive window, >the scrollBar hilitings disappear, so if you select this window, the >scrollBars will appear, but they will be inactive. >I thought that the sample program can help, so there is the source: >.............. The source is rather big, so I've deleted it - if it's interesting, I can e-mail. >From DTS answer: >.......... >I am still trying to track down the root of the problem concerning the list >manager.

Hi everybody!
As I promised, I'm sending the next bug confirmed by Apple:
=====================
To: MACDTS@AppleLink.Apple.com
Sorry, I have to report one more bug (I think).
This is a very simple one, so I don't include an example this time.
Subect: TextEdit ROUTINE TextBox
Condition: There is a simple "optimization" in TextBox routine, I
think. When the routine sees that the text can be drawn in
one line, it draws the text with DrawText routine, without
creating a TextEdit record.
Problem: everything is O.K. while the box is tall enough. If the
Box height is less then the font height, the text is drawn
below the Box (TextBox doesn't create TextEdit record, and
doesn't clip the port to the Box itself).
Am I right ?
=======================
Message-Id: <668800133.3360259@AppleLink.Apple.COM>
Subject: RE-Bug Report
To: BUTENKO@TWIN.SRCC.MSU.SU
From: MACDTS@AppleLink.Apple.COM (Macintosh Developer Tech Supt)

Hello Vladimir,
Thank you for sending us the bug report on the TextBox routine. I verified that
it is indeed a problem, and sent it to our Bug Reporting Center. The best work
around for now is to call ClipRect yourself before calling TextBox, as I'm sure
you have already discovered.
Best Wishes for your continued success,
Gordon Sheridan
==========================
I hope it will help somebody somewhere some day...
