Copy-Paste form external sources does not work on Windows 8.1

by Dominique B.

Hi dear all, I am currently taking a couple of tutorials on Pharo and I noticed that cutting and pasting code snippets from the web, pdf, notepad, ... to Pharo 4.0 was not working on my Windows 8.1 installation. I double checked that versions 3.0 and current 5.0 exhibited the same behavior on 8.1.I double-checked this problem does not manifest on Windows 7. Am I the only one to experience it?Thanks in advance,Â Dominique

yesâ¦ I introduced that problem in Pharo 5. If you are using that version right now, it is my fault :) (but is Pharo 5 pre-alpha so we are ok with this instabilities for nowâ¦ I will solve that after ESUG) cheers, Esteban > On 14 Jul 2015, at 14:51, Blondeau Vincent <vincent.blondeau(a)worldline.com> wrote: > > Hello, > > I have the same problem and it seems to be random.

Hello, I have the same problem and it seems to be random. It is related to font cache.

Re: [Pharo-users] Pharo on 64bit Ubuntu

by Leo Noordhuizen

Markus, If you read the messages in this thread, you can see that it has been more or less solved. 'More or less' because Pharo runs fine now, but when I reboot Ubuntu I get a systemerror with as subject Pharo-vm. This has been probably caused by my different attempts to make this work (with different methods) which may have left some 'rubble' causing this. I should probably re-install Ubuntu soon. Which I do now and then anyway.

Searching for similiar projects

by Jigyasa Grover

Hello :D I am a newbie in Pharo and have started to build my first application i.e. an offline text search application namely *searchQuick* which returns the list of file titles from the pre-loaded text files present in the resource folder when a string is searched for. You all are welcome to fork the code (https://github.com/jig08/sQuick_new) , try the infancy application and send in suggestions. Further, I would like to request to put up my application on the CI Automated Build server for Pharo. I have already registered on INRIA and my request to join 'Pharo Contribution' has also been approved. Further, I am searching for similiar projects as sQuick so that it would be easier to put for automated build using the existing build. It would be great if someone could guide me how to find similiar projects or exisiting templates. Regards Jigyasa
