C2 freezes at trying to insert new object

Guys, I need your help.

Every time I try to insert a new object, Construct2 freezes. It started happening just now, out of nowhere.

Any suggestions about how to procede?

Last thing I did was downloading and opening the .capx: dl.dropbox.com/u/67034121/scirra%20construct2/New%20folder.rar

from this tutorial:https://www.scirra.com/tutorials/311/level-select

I already tried opening other .capx, creating new projects, restarting my notebook, but nothing works. I?m using the version 119, and just tested the last 123 beta released. same result.

Please, someone can help me?

What are your computer specs? Really weird.

Have you tried other computers?

Intel Core i5

2.30Ghz

6GB RAM

Windows 7 64bit

Graphic boarde: AMD Radeon HD 6470M (Offboard) and Intel HD Graphics Family (Onboard)

Didn't tried on other computers =/

It is really weird, because it started all of a sudden...

That capx ran fine on mine, no odd behavior after.

Did you try uninstalling completely, that's worked in the past for odd failings.

Uninstalled and re-installed the version 199 several times. Even the version 123 is presenting the same problem.

Now I uninstalled and restarted my notebook, deleted the C2 folder with the remaining files. I'll try to install it again.

EDIT: Ok,guys, problem solved! It were a matter of complete stupidity from my part. I normally work with my notebook plugged with a monitor, extending the desktop. But now i'm just using the notebook screen, and in spite of using the single screen option, the new object pop-up was opening off-screen.

Thank you all for the help! And sorry if I caused any trouble.
