-- Bug description --
I just installed Scilab 4.1.2 I have a problem when I try to use the
Scipad. When I try to save a file (any file!) as a "Scilab File" the
program just crashes. When I save it as a "Scicos File" it does not
crash. However when I then execute it from the scipad (with F5) it runs
but then crashes. When I close the scipad and just run it from the
console using Exec.. it runs normal.
I have no idea how this can be caused. I'm using Windows Vista Home
Premium, and like I said, I use Scilab 4.1.2. The program gives no
error message, it just doesn't respond anymore.

"the program just crashes" "The program gives no error message, it just doesn't respond anymore"
Could you be more specific about what is crashing exactly? Scipad? Scilab? Both?
I have to say that technically from Scipad there is absolutely no difference if you save your file as a Scilab file or as a Scicos file. This is handled in Tcl/Tk on which Scipad is built, not in Scipad itself.
I can't test in your exact case since I don't own your non free OS...
When you select "Save as..." from the file menu of Scipad, the file selection box opens, right? Then you type a filename and select the type of the file in the combobox, still right? Then Scipad crashes instantaneously and with no error message when you click on OK in that dialog, can you confirm that?

I have the same problem, and found this thread upon querying the list of bugs.
I am running 32-bit Vista Business. When I open Scipad and try to save the current file with any name besides "untitled.sce", scipad hangs. If I click on the console window and click back to the editor, Scipad unhangs, but the filename on scipad doesn't reflect the new filename I tried to enter. Then, if I try to close Scipad OR the console by clicking the upper-right-hand X, it is unresponsive. No error messages are generated and there is no prompt to log the error.This happens in both 4.1.1 as well as 4.1.2.

OK, since the original poster didn't answer my post above, are you ready, Kevin, to help me in fixing this bug? I would ask you some questions and also you would have some tests to perform.
I don't have Vista and I have no intention to buy it, be it for fixing Scipad bug.

I have the same problem running Vista 32 and Vista 64. Love Scilab in XP but times change and had to move to Vista.

Reproduced on Vista Business.
For some unclear reason probably linked to the way Vista manages grabs on its windows, for me the problem goes away if in:
SCI/tcl/scipadsources/filecommands.tcl
I make the following three changes:
-
Lines 640-641: set file [tk_getOpenFile -filetypes [knowntypes] -parent $pad
-initialdir $startdir -multiple 1] becomes: set file [tk_getOpenFile -filetypes [knowntypes]
-initialdir $startdir -multiple 1] -
Lines 922-923: set myfile [tk_getSaveFile -filetypes [knowntypes] -parent $pad
-initialfile $proposedname -initialdir $startdir] becomes: set myfile [tk_getSaveFile -filetypes [knowntypes]
-initialfile $proposedname -initialdir $startdir] -
Lines 929-930: set myfile [tk_getSaveFile -filetypes [knowntypes] -parent $pad
-initialfile $proposedname -initialdir $startdir] becomes: set myfile [tk_getSaveFile -filetypes [knowntypes]
-initialfile $proposedname -initialdir $startdir]
i.e. when I remove
-parent $pad
in all tk_getOpenFile and tk_getSaveFile instructions.
Before committing this change, I would like to get confirmation from those who see this bug that my changes above also fix the problem on their machines.
Please provide feedback here.

PS: Yes I know, there is another tk_getOpenFile in scilabexec.tcl (proc importmatlab), but let's first confirm the above.

The problem doesn't happen in Vista with scilab-5.0-alpha2, which ships with Tcl/Tk 8.4.18.
Not sure my above proposal (comment #9) should be committed.
The -parent option in tk_get*File is here to make the scipad window the logical parent of the file open/save dialog. The file dialog is displayed on top of its parent window, and this is desirable and intentional.
With -parent $pad, no action can be done in Scipad before closing the file dialog. Without this option I can imagine a number of side effects if the user is nasty.
I'm wondering if we shouldn't just make no change at all to the scipad codebase, based on the observation that it works OK with recent Tcl/Tk versions, and leave the workaround here for users to make their changes themselves if they want to stick to Scilab-4.1.2 and Tcl/Tk 8.4.15.
