Problems/Suggestions with Pharo IDE

Hello,

I'm a French student who have learned Pharo for 2 months during a university course.

As this was the first time I use Pharo IDE and the first time I program in Pharo, my teacher suggested me to send a mail on the mailing list if I encounter problems.

I encountered some problems/suggestions with using the IDE :

As I crashed the IDE several times, is there a way to automatically save the image every 5 minutes (or every other frequency) to avoid the loss of my work ?
I can't copy/paste from Google Chrome (on ubuntu 14.04) while I could copy/paste from other software like Gedit or Firefox.
Last problem that I have seen, is that I couldn't use Pharo on my windows 10 Computer. I have downloaded the last version (windows version) on pharo.org and when I try to execute it (without and with administrator mode), I have a pop-up who appear. I made a screenshot of this pop-up and put it in attachment to this mail.

I hope that I have posted this mail in the good mailing list.

Thanks for reading,

Clement

This is almost impossible to lose code in Pharo ! Your code
modifications are logged in the changes file.
Please have a look to this video that explain how to recover changes
when you crash you image:

Nice to hear from someone new to Pharo taking the time to let us know
how to improve. I hope you have a long and prosperous experience with
Pharo.

Could I just clarify if this was a "crash" where the Image exited, or
a "lockup" where the Image froze. Since the code you develop and
execute runs in the same thread as the IDE, an error in you code that
(for example) loops forever will block the UI from operating. Do you
know about the system escape keypress [Alt .] "alt-period" for
breaking out of such a situation?

I'm on Debian 8 Jessie which uses MATE Desktop Environment 1.8.1. Its
similar vintage to 14.04 but I don't know what desktop it uses?

I just downloaded the latest build 50636 and tested against Chrome. I
had no problem copying text from a random web page into a playground
in Pharo. But I may have a different VM. Could you post the exact
links you downloaded, and also the VM and Image shown by World menu >
System > System Reporter. Here is mine...

I had the same problem. There is a little trick to resolve this: [1]
(second message).

Sadly, there are still webpages where copy/paste from it to Pharo does
not work :(.

You can access the Process Browser to stop the process.

This is not such a good idea, it would/could do more harm than it helps. Especially for a beginner. Just my opinion.
