When I click an item it just becomes less visible. HELP!

[BeCreative]

So I've set up my items and tested the program; it works good. But then I think I did something in settings and for some reason when I click an item to launch it, it won't run! Instead, it becomes less invisible whenever I click it till it's actually invisible.. Also, all of my items are .exe

HELP ASAP.

That sounds rather odd.
Just a thought, but maybe you have some kind of hijack virus/trojan.
If you click a non-.exe file, what happens?
For example, if you double-click a .JPG (image) file, does it load into the correct image viewer, or what?
