Yesterday, I installed the last build 141.352 on my new MacBook Pro with OS X Yosemite v.10.10.2, and I have a very weird behavior when I create a new project and start typing in the editor. At the beginning I just cannot type anything, different buttons give some random behavior like delete line, delete word etc. After a few seconds of random typing it starts behave normally, and I can type what I want. But if I switch to a different document, again I have to push some buttons randomly until the keyboard starts to behave normally. If anybody have such a problem? Do you have any idea why it can happen?
