BUG???

Hi, I'm making a main menu for a game and I have trouble doing it.

I want to put three button: play, credits, and options.
When the mouse rollover them, their colors will change.
I succeed with the play button, but when I tried on credits and options button, they will disappear when we rollover them.

I tried to close and open the app. again and I met other problem.

Those two button sometimes changes color or disappears whenever we rollover them.

Is that a bug?
How can I solve it?
Thank you

Other problem:

I tried to close and open the app. and my app. player stopped working.
There's a window opened said:
"Multimedia Fusion Editor Runtime has stopped working.
A problem caused the program to stop working correctly.
Windows will close the program and notify you if solution is availabe."

Is that connected with the problem I faced before?

Have you defined all the images necessary for the button to work? It looks like it is missing the rollover image...

Hi, Francois
Thank you for answering.

Where can I find the images?
Thank you

Well, you have to draw the images by clicking edit in the image property of the button.

It worked! Thank you very much.
