Apologies for the vague topic title but I couldn't write all I wanted.
Today I had a funky situation with C2. While I can't tell if it's a bug it sure doesn't seem intentional anyway, so here's what happened, step by step:
Open Construct 2.
Select "Browse Examples".
Drag and drop an example file to C2 (don't close the Examples folder).
Preview it in a browser tab.
Close the browser tab.
Return to C2 and close the project.
Maximize/return to the folder again.
Drag and drop another example.
Launch it in the browser.
While previewing, the sprites/effects of the last opened example replace whatever sprites/effects are present in the newly opened file.
Imagine my surprise seeing this:

Yes, those are several copies of the plumber sprite swaying like grass in the Sine behavior example <img src="smileys/smiley36.gif" border="0" align="middle" />. To replicate it follow the above steps and open the "Pick Nearest" example first, then "Sine behavior - grass". I also got standard "shiny" sparks in what was meant to be the Explosion particle example.
I'm using Vista and the latest Firefox version (which got updated fairly recently - yesterday if I'm not mistaken?). And C2 r111, of course.
