GUI buttons become unresponsive after clicking any of them (Windows 8 64bit)

[hcarty]

This is on a Windows 8 64bit installation, using the recommended OCaml installer and ocaml-top 1.0.0.

I can consistently reproduce this problem by starting a fresh instance of ocaml-top and clicking the 'Run' button. The application's GUI buttons become unresponsive but the window buttons (minimize/maximize/close) continue to function. If I move the mouse pointer around or possibly just wait 5-20 seconds the UI becomes responsive again.

During this unresponive time I am able to use the editing portion of the application.

Just in case, you don't happen to have any previous installation of GTK on that machine ?

[hcarty]

I'm fairly certain that nothing with Gtk has been installed on this particular machine, aside from ocaml-top.

Ok. Thanks for the report, I hope I can find a way to reproduce. Does that happen just at startup or after any use ?

[hcarty]

It happens at least after each press of the Run/Restart/Run to end buttons.

I'm clueless, works like a breeze on windows 8 64 here...

I'll see if I can find anything special on the affected system.

You can activate some debug information by running from a console with environment variable OCP_DEBUG set to 1.
