Scott,

I launch it from the dock. Thanks for the tip. I'll try it from a terminal window.

Arthur,

I have also experienced this exact problem on OS X 10.11.3. But I've noticed that it only occurs when I open CoqIDE from the launchpad. If I instead invoke it from the terminal, I do not experience this issue. If you used the .dmg installer like I did, you'll either need to add <Coq install location>/Contents/MacOS/ to your $PATH variable, or soft link the coqide binary into your /usr/bin. Then from your working directory, run

$ coqide &

Best,

~Scott

Hello,

An issue similar to what you describe has already been reported. We
suspect that it comes from a GTK bug under OSX but we are still
investigating.

Sorry for the inconvenience.

Maxime.
