  For list-related administrative tasks:
This is not a DrScheme problem : your 2 DLLs (opengl32 and gdi32) are
out of sync.
Do a google search with "opengl32 gdi32 gdiswapbuffers", and you will
see that your are not alone with this kind of problem ;-)

Thanks.  I copied over the other version of OPENGL32.DLL into the
C:\WINDOWS\SYSTEM directory and this fixed it.

Objet : [plt-scheme] Error in PLT Scheme 202

  I just completed download and install of PLT Scheme 202 on my Windows
machine.  I performed the installation including creation of ..zo files.
No errors
were reported during the installation; however, when I try to activate
I get the following pop-up box error:

    The OPENGL32.DLL file is
    linked to missing export GDI32.DLL:GdiSwapBuffers.

I did a search of my C: drive and found the following:

    I have the OPENGL32.DLL file in the following locations:

            C:\WINDOWS\SYSTEM  - size=699,664 bytes, ver=4.00
            C:\Program Files\Maple 7\BIN.WNT - size=733,296 byes,

    I have the GDI32.DLL file in the following location:

            C:\WINDOWS\SYSTEM - size=155,648 bytes, ver=4.10.1998

I had PLT Scheme version 103p1 installed, and it was working fine.  I
did completely
remove it before installing the 202 version.  I discovered the problem
initially when I
installed the recently released (and posted to this list) "Catalogs"
program, and after
installing it (again with no install errors reported) tried to activate
it and got precisely
the same error reported above.  I deduced from this that I probably
needed to update
my version of PLT Scheme to get "Catalogs" to work and of course got the
I have described.

Since I have a large number of other applications running fine on my
Windows 98
installation, I suspect this is an error in DrScheme; however, I have
seen nothing
so far in this list of anyone else having problems with the version 202

Can anyone help me out.  Thanks very much.
