DELPHI 3 and 4 LOCKUP PROBLEM

Subject:  Re: Delphi 3 problem

I've had that same problem. The problem are some controls (I haven't got
round to fully fixing this).

Try this:
Create a new folder under BIN, and name it "Old DPL files".
Move all the files with DPL extension from the BIN folder to the new
folder.
You can now run Delphi 3. You will, of course, be wanting to use controls,
so move some (at least the standard controls) back to the BIN folder, and
then Install those packages.

Good luck and happy coding!

Subject:        Delphi 3 problem

I've just installed D3 of my pc, but it won't run.  It simply freezes up
when the title screen comes up.  To begin with I thought it might be a
problem with my processor.  (I have acyrix chip, NOT INTEL.  Does anyone
know of a problem with delphi and a cyrix 686 MX?).

However, I now feel it may be the Registery that is causing the
problems.   When I first installed D3 I still had D2 installed.  So, I
uninstalled D2 and D3.  Then re-installed D3.  And now have this
problem.  It has been suggested to me to reinstall D3 in SAFE MODE (in
win95).  Does this work?  Are there any alternatives other than totally
wiping my disk and re-installing everything?

Has anyone else had this problem and overcome it?  Any help would be
much appreciated.

Jamie,
This problem is caused with an S3 video card set at 800x600 resolution or
more. You have two alternatives if the problem is due to an S3 card.
1. You lower resolution and color (256 color).
2. Change the card to Cirrus logic or better.

i had the same problem when ugrading to win98 and delphi 3 stopped
working.
i pinned it down to dirextX.
an early version of DirectX 5 ( early 98 )wou;d work but any later
version up to v6 would cause delphi 3 to lock up.
--------
I had a Cyrix 486 a couple of years ago and it had problems with some
programming languages (esp. Visual C++ - according to MS a small bug - It
would'nt produce a .exe - I call this a major problem...),  It would run D2
fine, slowly but fine.  The Cyrix chips have a different caching logic
which caused the problem (in the 486 anyway). Try contacting Borland and
see if there are any problems with the Cyrix 686 chips and Delphi.
--------
You may be interested to know I've found the true cause of that D3
problem.  There is a with D3 and D4 and the video chip s3.  So, if you
have and s3 ViRGE graphics card or Trio64 then you'll have this problem.
The only REAL long term fix is to get a new graphics card.  A short term
fix is to turn the display acceleration off in display setting in
Windows.  It needs to be set to NONE.

Another alternative is to use your pc in VGA (SAFE) mode.  But this
obviously isn't very practical.

It is a known bug.  But its not really a problem with Delphi as such,
its a problem with Delphi and s3.

        Yeah, I'd agree with updating drivers if possible.  But also,
screen colour and resolution is a contributing factor.
--------
        Do you have an s3 video card (s3 Virge or Trio64)??  If so, then
there is a known problem between Delphi and s3.  The way to fix it is to
go into display settings in Windows and turn the display acceleration
off, set it to NONE.  It will then work fine.
        If you want to have acceleration back on full, you will need a
different graphics card.

i've had the same thing happen.
I pinned it down to being to do with a version of DirectX greater than
an an early one of version 5.
someone else on this list has said that it may be due to using a  S3
video chip ( which i have )
his solution was to disable the 3d features of the card from the control
panel.
