Images – another wee problem

Here’s what I’ve been doing so far. It has worked every time previous to this and also this morning.

Creating a page. So i create my page and save it. I go back into “manage pages” to start adding content. The first thing i do is click on “add media” to add a photo.

Now normally, the front page would open up to let me browse on my computer for the picture I want.

It has stopped doing this as of this morning. It doesn’t come up with the browser box anymore (or it does appear but for a few seconds only) – it just says “choose files to upload” “After a file has been uploaded, you can add titles and descriptions.”

Nothing happens if you click on “choose files to upload”

Any ideas? I can’t upgrade as yet – my web designer did this for me and is currently doing a ski season (with no laptop)

thanks!
