[Pharo-users] SDL2 and fork

Hello everyone, I tried to use the SDL2 binding to Pharo to create a very basic 2D application (just some sprites and events) and it worked great. The issue I have is that when I start my application, as long as I have an active SDL window, I can't use my Pharo image anymore (it freezes). To solve this problem I tried opening my application in another thread by doing so : [ (MyApplication new) start. ] forkAt: Processor lowestPriority. (If I don't chose a low priority it changes nothing) The problem is that even if it kind of works, it is really slow and it slows my whole operating system as well (I use windows XP) How can I fork more efficiently or open a SDL window without losing control of my image ? Thanks, Matthieu
