Because it occasionally crashes for me, or is it just my computer?

My sprite has platform behavior, and the jump was set to the shift key. When I run the game and press shift, it doesn't move upward. I don't need it to be standing on something solid first do I? Will it move upward when gravity is zero?

And as for the objects, for some reason I can't find the categorize you're talking about. I downloaded the version that's in the Download section of this site, so it should be the 0.98 version.

My projects tab on the right doesn't have any folders, just the name of the application its layout sheet.

And when I click on an object in the objects list there is no "category" in the properties bar.

And I'm trying to get my character to jump, but it wouldn't. The lesson 2 on the platform school tutorial has jumping, but I can't figure out what he did to enable jumping. Where did he set jumping? because I can't find it in the event sheet.

Is there a good way to do so? Can I group object together that have similar relations/purpose in the list or do I have to put them on separate layouts? If so, how do I move object sfrom one layout to another? Thanks

I found the making groups you talked about, but can I move previously created events into the group? Or would I have to make a new copy inside the group?

And does the platform tutorial tell how to transition and make new levels? (I'm almost done with the Ghost Shooter tutorial at the moment)

Is there a good way to organize events on the event sheet editor?

And how do I make multiple levels in a game?

I keep enlarging the size of the sprite when I left click in the picture editor. I'm doing the first tutorial, and I'm setting an image point. Everytime I click on the mouse to set the point, the sprite gets bigger. And as a result the image point is not at the spot I want it to be because the sprite is a different size.

And sometimes when I click in the canvas, the image looks broken in the editor, like another copy of the sprite is overlaping the other. What do I do?

Also when I scroll in the layout editor, the layoutr zooms in while I move, and then zooms out when I stop. Is that supposed to happen.
