Our program mainly consist of two parts:
the scilab script and the tcl/tk script.
Compared with scilab scripts which are small,clear and consisted only of compact algorithms,Our tcl scripts have a lot of
bugs(and partly because we can't get a tcl interpreter with good enough error-reporting).
We have tried our best and fixed most of them,but we can't promise anyway:)
If any new bugs or troublesome problems were found,We will be very pleased if you contact with us!!
Here are some Bugs fixed or infixable maybe you are interested in:

1.speedup
we have talk a lot about the speedup in our documentation.
We write this troublesome functions only because we want to fix the "typing bugs" of the tcl interpretor of
scilab2.6 for windows.
A lot of problems when Speedup is turned on,view our documents for more details.
We strongly recommand you to use Scilab2.7 Windows edition or just use the linux version.Don't forget to choose VRScilab
with correct edition.Speedup is legacy in new edition.

2.the "spaces bug" under Scilab2.7 (fixed)
We found that tcl/tk interpretor of Scilab2.7 have new kind of bugs.
it's strange that when we "ScilabEval" a string ,first letter of each line in the string will be ommitted.
As you may guess,We write a functions to add some spaces before eachline:)

3."tcl enviroment bugs" (fixed)
We make the GUI interface using VTCL,it's really a very convinent tools and save us a lot of time,thanks for the author.
And we all know that tcl is a wonderful language with platform independence.
But we found that some commands such as "SystemWindowsText","SystemWindowsColor"(generated by
VTCL).. failed under linux.
So finally,we had to use "specific properties",this's also an important reason that we make a special linux edition.

4."vrml bugs"
Some will complain that the vrml files(.wrl) our software we generated is too huge that make the system very slow
when view.

Well, We admitted that the file is huge----Because we are use all the data and the same plotting form the same as
plot3d,plot3d1,param3d.....in Scilab.That is ,when you want to plot a sphere in Scilab,you have to use plenty of
squares to form it. And we form the vrml files in this way although the vrml have a "sphere" Markup.
But as you can see,we can judge the shape of the object by no way. So it turns out a fat file.

But, we don't think the fat file will make your system slowdown.
We guess that you are using Linux with VRML plugins such as "freewrl". We found no tools or plugins works good and
fast enough under linux.
We recommanded you to view the VRML files under linux.There are plenty of VRML viewers under Windows and all works
very fast.We have tested a file big enough(about 30MB),it works quit fluently.

5. plotting hole bugs
I f any of your variable pass to the plot function constains %inf, it may fail to generate the VRML file under Scilab 2.7, so if you want to make a "hole plot" VRML graphic, try it in Scilab2.6.

6.Illegal link bugs
It seems that on some system,sometimes,the "2min_guide" and "index" documentation link in the menu doesn't work,we are confused about it but can do nothing to fix. Refer to our document directory instead when it fails.
