Hi all, Some time ago I found out that half of the time spent in opening a browser was spent in ScrollBars code (you can see it by doing TimeProfileBrowser onBlock: Object browse). So I looked at the code and as it was messy I made a big refactory and cut browser opening time a bit. The thing is I never submitted that code because it wasn't fully working, and as I didn't know if this kind of random refactorings were welcome I didn't take the time to finish it. I found it some days ago rotting in my filesystem. Then the question is, would you be willing to include the code in next iterations of pharo? I can rebase the code to make it work Pharo1.1 and send it for review. Regards, Javier. -- Javier Pimás Ciudad de Buenos Aires
