### Re: Install on Windows

Hi - I noticed the same problem with the icon, but I was able to download
the .exe version without having to rename it.  Also, the startup time on my
NT machine is shorter than the 30-40 seconds you mention.  Otherwise, no
problems.

Win 98.  It could be a color depth issue, or perhaps it's the NVIDIA
card?  I tried it on one other computer (also Win 98) and didn't have
this problem, so it obviously isn't Windows 98 itself.

Where can I find such a converter, please?

I'm noticing this too - I've even increased the timeout in xmaxima

### Re: Install on Windows


Dear James,
Dear Mike,
Dear Cliff,

Next, the Maxima logo in Maxima Primer (intro~1.html) looks
perfect in a white background. No problem for my Windows
Millennium Pentium computer at 850 MHz with (at least) 256 MB
memory, but I had some problems in displaying 3D plots (a rather
usual situation).

On the same machine I have experimented with start-up times
between Maxima 5.5 beta and Maxima 5.9.0 rc4 (under
exactly the same conditions) both original start and restart.
My conclusions are that Maxima 5.5 beta constantly requires
3 sec, but Maxima 5.9.0 rc4 requires 10 or 20 sec. This happens
both in start-up and in restart. For 5.9.0 rc4 I suspect that 20
sec appear mainly when other programs are in use and, in
a Maxima session itself when few commands have been already
computed (the usual case) and this is rather unfortunate, since I
frequently use the restart option when in some difficulty or in a
new problem. (With no commands or just a trivial command,
I tested 1+1, 10 sec generally at restart.)

I have also mentioned in my message yesterday that

### Startup times on Windows

This may be an operating system issue: Windows 9x (including ME) vs.
Windows NT (including 2000/XP).  Nikos reports terrible start times
under Windows ME, and Mike and CY report terrible start times under
Windows 98.  My start times are fine (about 2 secs) under Windows 2000
(1.0 Ghz Athlon with 256 MB of RAM).  XP is supposedly faster for things
like this, but I don't have it.

A very quick Web search shows that Windows 9x is still very widely used.
Among users of Shockwave, for example, W9x/WNT are about 50/50 as of
December
2002(http://www.macromedia.com/software/player_census/shockwaveplayer/us
er_profile.html).  Of course, we don't have statistics about our "target
market" of math hackers, but the fact that at least three people on the
list are still using 9x shows that it *is* relevant.

Details:

On my machine, 5.9.0rc4 takes < 2 sec to start, and 5.5 takes < 1 sec to
start.  These are warm start times, that is, that is, there was a
previous invocation of Maxima which I killed -- so DLLs and so on may
still be memory-resident.  Restart time on 5.9.0 is about 1 second.  I
also tried to simulate a cold start by using a large amount of memory in
some other processes (which I then killed), and in that case the start
times were both about 3 seconds.  I suppose I should try after
rebooting, but I'm too lazy....

### Installation on Windows - (Fwd) Re: update on socket problem

Hello,

Here is, I suppose, the message I posted on the list,  Cliff is speaking
small versus big partitions, ans post the result.

But I believed, from a message of J Amundson, just after mine that he had
understood where the pb came and had corrected it?

Yes, it is a bit annoying on slow machines. But maxima.bat opens Maxima in
1 s in
a command window, while xmaxima.bat opens it in 45 s, in a Tcl/Tk window,

### Re: Startup times on Windows

Some more weird statistics on startup times.

Windows Me on Celeron 500Mhz with 256Mb RAM:
Start 3 sec, restart 2 sec.

Windows XP on Athlon XP 1700+ with 512Mb RAM:
Start 5 sec, restart 4 sec.

Same machine (not similar but literally the same,
this is multiboot machine with several OS'es)
but with Windows Me:
Start and restart more than 20 sec. Restart
may be even timed out.

Windows 98SE and Windows XP on Pentium III 733MHz
with 384Mb RAM:
Start and restart times 2-5 seconds. Win 98 a bit
slower.

Notice that on _all_ machines and OS'es maxima.bat
starts almost instantly. I

I also tried old Maxima 5.5 on this especially
troublesome Windows Me installation.
Start time is less than 1 second, so definitely
there is some strange point in either xmaxima
script or Tcl/Tk Windows implementation.

### 5.9.0rc4 on Windows

I have a problem with 5.9, not existing on 5.5, do you see it also on linux?
In xmaxima, if I type something like 4*5; in the LOWER window and then go to
edit, change to maxima and chose mark for evaluation I get an error message
about a ] after quote instead of a space. This makes the lower window
useless for "notebook" type use a la Mathematica.
