I have just loaded Construct on my Toshiba Satellite Pro 6100 with 1 gig of RAM and a P4 with Win XP.
I tried to simply click to add a sprite, when I do this the sprite editor starts to open and I get an error box. After clicking OK Construct crashes.
The error box says invalid texture was referenced, this is a bug report it!
I am including a screen shot.
So anyway I would love to have this program work for me.
