Hi, I got exactly same issue here with Construct 2 Release r139
uninstalled / reinstalled
Freeze on "add event" (the window popup does not show)
Tt was working great before. I was working on a big project, then I made a 2 weeks pause.
What may have changed on my computer ?
I may have installed a few games, maybe a graphic drivers update has occured. (Nvidia, geforce 9800GT)
I hope this will be quickly fixed, the project can't go on :/
