Thanks for the response, tobychapman!
I did a search for the 'Please wait...' text but unluckly the iDEAL payment file doesn't work this way.
I noticed that indeed most payment files have this message towards the end, but like a few other files the iDEAL file don't.

Somehow the iDEAL payment method redirects customers to payment_wait.php.
If I could locate the code (or file) that's responsible for that action, I could try to change the redirect to a new payment_wait.php with a different message.

Any idea where to look for that?
Thanks again!
