Component Palette Corruption Problems
Question:
I installed Delphi 3 successfully, no errors occurred. Delphi 3
starts up O.K., but the component palette display is corrupted:
part of one icon appears into part of the next, images "drifting"
off the buttons, the wrong images on buttons, etc. Restarting the
computer does not help. What's going on?
(Note: Similar cases have been reported from Delphi 2. Same
workarounds/solutions may also apply to Delphi 2.)
Answer:
The problem is most likely a compatibility conflict with the
video driver. Borland tests it's products against generic S3
drivers provided by Microsoft or S3 Inc. Any drivers compliant
with this standard should not cause this problem with Delphi 3.
Video drivers that are not compliant of this standard may or
may not function correctly with Delphi 3. Refer to Part I and
Part II if you using any of the following high performance video
card types with Delphi 3: Matrox Millennium, Neo Magic, or a
"Non-Standard Hotrodded S3"* Card. Otherwise, refer to Part II.
*(A video card built around the S3 chip and which is running
drivers that the vendor has added performance tricks to above
and beyond the generic S3 drivers. S3 chips are used in several
different video cards from different vendors (STB, Orchid,
Number9, Diamond, etc.))
Part I.
It has been reported that certain workstation configurations
that include the above high performance video cards, using their
default high performance video drivers, may cause the Delphi 3
component palette to appear corrupted. Borland and cooperative
video card vendors are currently investigating these reports.
See Part II if the following workaround/solutions are
unsuccessful:
Matrox:
Borland and Matrox are investigating the issue, but neither have
been able to reproduce the problem using the Matrox Millennium
video card. Possible workarounds that customers have reported
are:
-Turning off "bitmap caching" in the Matrox driver options.
-Switching to 16 bit or 24 bit color mode.
(Contact Matrox for Support on these workarounds.)
Diamond:
For The Diamond Viper 330, Diamond has advised using the generic
S3 drivers provided by Microsoft or S3 Inc. as the solution for
their video cards.
(Contact Diamond for support on this solution.)
Neo Magic:
For The Neo Magic 128XD video card, a reported workaround is to
change the video mode to 16-bit or 24-bit color.
(Contact Neo Magic for support on this workaround.)
"Non-Standard Hotrodded S3" Cards:
Contact your video card vendor about getting a compatible generic
S3 compliant video driver. Also see Part II below.
Part II.
Try running Delphi 3 under Safe Mode in Windows 95 or VGA Mode
under Windows NT. This loads only standard-generic video drivers
which are compliant with the standard S3 drivers provided by
Microsoft or S3 Inc.
If this fixes the display of the component palette, then the
problem is most likely a compatibility conflict with the video
driver. You should get an updated version of your video driver
from your video card vendor or switch your default driver to a
generic compatible driver from Microsoft or S3 Inc. (which may
be available on your Windows 95 or NT CD).
As of this writing, the above workarounds are the only ones
known to Borland. Since Borland and the related video card
vendors have been unable to reproduce this issue, these
workarounds have been provided by Borland users, and have
not been directly tested by Borland. If these workarounds
do not solve your issue, then please post a detailed message
to Borland's Newsgroups (see:
"http://www.borland.com/newsgroups/", please post to the forum
"borland.public.install.delphi") and/or contact your video
card vendor.
