Digital Workshop

I am developing in XP, but need my finished product to work in Vista. Having worked at it for months, was getting very frustrated in how the program performed in Vista until just now!

I have been developing a program to help children learn to read, and on one page had 26 buttons, and when the mouse moved over each of them, they played a letter sound (wav file).

In Vista, when I ran the published program, the mouse seemed to freeze for a split second when trying to move over any of these buttons, before playing the sound. This problem NEVER occurred running in XP.

What I did today was, for just ONE of the 26 buttons, selected the option that the sound should be pre-loaded. I didn't do this for any of the other sounds. And hey presto, the fault has gone.

thought other people might be interested to read this, but also was wondering if anyone could shed any light on the reasons for this happening, as it appears to me to be most bizarre!

Thanks,

Paul

It's interesting that preloading one sound eliminates the problem you have.
It is best to preload sounds that are required instantly, otherwise there will be a slight pause as the sound file loads before playing. On some systems you will see the effect you mentioned.

Triggering sounds on mouseover can give problems when Opus tries to load sounds in rapid sequence.

I would also convert the WAV files to MP3. There is a huge difference in size and for normal speech, you can use mono and relatively low 'quality'
