Alice crashes every other time
 
For some reason, the 3/01/2012 version of Alice I'm using crashes every other time I run it. :confused:

The first time I run the program, it just gives me an error and crashes. Then I have to end the process in Task Manager.
The second time, it loads up quickly and with no problems.

That happens to me too. Not sure why or how to fix it. Best thing I could recommend is delete and re-download Alice.

Bizarre. I'm using that version, but this never happens to me.

I get that too.

Using Windows 7 64-bit, if that makes a difference. It leaves the splash screen on the desktop, and has to be killed with Task Manager.
:(
It doesn't happen often; usually when I'm forcing an Alice re-boot after making a change.

Further testing today

Have tried several options including moving the newest Alice 2.2 folder into the Progrm Files (x86) folder in my Windows 7 64-bit workstation. The problem is strangely repeatable.
I can start and quit Alice 2.2 3/01/2012 as many times as I want with no problem, as long as I don't do anything. However, if I load a program before quitting, Alice will crash with the mentioned error the [U]next[/U] time I start it, and it must be killed via task Mgr.
The same error is also repeatable using slow and steady Alice 2.2.

Something done when loading an .a2w file makes the difference. The file doesn't have to be modified, nor saved. The thought occurred to me that it might be incompatibility between the newer version and older .a2w files, but creating a new world with just a bunny, saving it, quitting, and restarting Alice generated the same error.

All testing was done using original downloads with no modifications.:(

Update: Notice that Alice 2.2 required/jre folder is using jre1.6.0_25, while my system is currently running jre version 7_5.

Update 2: Tried using the current download on a classroom 64-bit CPU workstation with a 32-bit install of Windows 7. Exactly the same problem, so it is not isolated to 64-bit O/S.

Start up window bug
 
The bug was caused by a failed initialization of the selected tab. The error will only occur if the "Open a world" tab was selected the last time Alice was opened. To temporary fix this problem, make sure you create a new world before you close Alice. That will then leave Alice with the "Template" tab selected before closing.

Please release a patch
 
My School district restricts Task Manager for student logins, and in some cases, teachers.
A students only recourse is to logoff and back on to clear the frozen program, which wastes time.

Will this get patched soon?

Just out of curiosity, does it restrict security options, Ctrl-Alt-Del, or does it actually restrict task manager? Because if it's just security options, you can use the Ctrl-Shift-Esc shortcut to get to task manager.

Not Important
 
Haven't been back to campus this summer. It would be nice, however, to have the bug fixes released before the end of July. All workstations will have a new image by then, and I will need to install the software packages that I need for my classes.

I won't install or use packages that are known to have significant bugs.

Maybe its because your using hotspot shield. I am and that's when I started getting the same error.

JV018 08-21-2012 03:16 PM

My students have the issue of the program frrezing and not letting them close it. I have the same issue with task manager. WE are able to open a 2nd Alice window but would like to fix the issue of the program freezing on the students? We had the same issue with our old laptops as we do on our new laptops. We just reloaded the program today. Does anybody have any ideas on how to fix this problem?

MrMoke 08-26-2012 02:36 PM

Version 2.3 fixed it.
 
Thanks Don
