Kinda OT: lost my alpha channel

Before I was able to start a new image in PSP 6 at 655x480 with the backround as transparent paste or draw a layer then save as a .png . then import it into Vegas and the backround would stay transparent. Now its not.
In the media properties I 've tried the various alpha cannel settings (to be honest I dont think I have a handle on what each choice ie; straight,premultiplied etc does, That'll be one of my suggestions of coverage for Spot's new book)
Actually I thinks its something I'm not doing or forgetting in PSP. I did a search, anybody with suggestions or a link to go for more info on alpha channels.

Right click the image, choose properties, media, alpha channel and select premult. It will become a transparent image. I'll explain more about the alphas in the 'budget' book I'm doing.
