[Bug 11765] New: Mathematica 5.1, too close to be usable.

http://bugs.winehq.org/show_bug.cgi?id=11765

Summary: Mathematica 5.1, too close to be usable.
           Product: Wine
           Version: 0.9.54.
          Platform: PC-x86-64
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: -unknown
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]

Hello.

I have previously filed a bug about Mathematica not being able to install:
URL: http://bugs.winehq.org/show_bug.cgi?id=11725

The problem was identified and Mathematica is able to install correctly. 
It also runs fine, but sadly is not yet usable because of the next reasons:

- Writing wrong Mathematical expressions which will lead to errors makes it
crash.
It is too often that expression will output errors like: "expression does not
converge", or "function can not be evaluated on x=...", or mathematical things
like that. So if after only one error, Mathematica crashes then it is not
usable.
Test with: f[x_]=x+3-
The last "-" sign must be followed by another expression. So this has to output
an error without crashing.
It also crashed when you write a clossing sign before an openning sign (maybe
because you are fixing an error).
Wine debug outputs of this is on the first attached file.
Mathematica reproduces a "chord" sound on each error which is not reproduce by
wine before crashing.

- Opening the Help Browser makes it crash after generating the help data.
Mathematica has a really usefull help browser, and it is a key feature. One can
not know what or how Mathematica can do its stuff without this, so unless you
are a complete expert on Mathematica, it will not be usefull for anyone.
Wine debug outputs of this is on the second attached file.

- Some charecters are not displayed as they should.
Writing an expression like: (2+x)/(x^2-3) will be showed as (2+x)}(x^2-3).
Note the "/" is changed by "}", but double "//" is correctly showed as "//".
Also Pressing x² makes Mathematica crashes just becouse the correct expression
is x^2 and not x² or x³.
Also there seems to be some conditions for the "/" to be drawed, like if it is
preceded by a variable o number:   see 1/x or x/(x-3) then the "/" will be
drawed, but if is is preceded by a ) or ] then "}" will be drawed:  (x-3)/x or
Sin[x]/x. Thats wear.

- Mathematical representation is badly printed as ascii.
When you enter expressions like (2+x)/(x^2-3) Mathematical has the really nice
feature of showing this as a nice looking fraction. Also it can represent it
with ascii characters if you choose that, but with wine, it doesn't shows the
goodlooking expression and shows a terrible badly drawed ascii expression. Just
to say, "1/x" can not be readed with this expression.

Also there is a non windows Mathematica console. It is Math.exe on the same
dirs as Mathematica.exe
It seems like it does work well:
Testing with wrong expression does not lead to any results and Mathe.exe
doesn't take it as an input.
Other expressions like:
 f[x_]=1/x
 f[0]
Does shows respective errors of complex infinite value.
No Plotting available.
No help browser available
No easy copy&pasting editor.

All this errors were tested on ubuntu 7.10 AMD64 and with wine 0.9.54 (becouse
.56 is not available yet for ubuntu on your repos) and with all builtin dlls,
but also some natives does the same results.

It is a big shame because it is unusable right now and with a few fixing, it
could be a Platinum.

Cheers
