eCart checkout wizard error

Hi,
Hopefully someone can help with this!!
When running eCart Checkout Wizard,on the Payments Section Step 1 of 1,I enter my pay pal member ID click next and receive this error - 'While executing onMouseUp in WA eCart CheckoutWizard.htm, a JavaScript error occured'. This message appears twice, and I can't get any further. I'm using Dreamweaver CS3 and eCart version 4.1.5. This has only started happening since i downloaded and installed the latest version. Previous version worked fine.
Thanks for any help
Colin

is this the same javascript error which was caused by line 310 of pages.js ?

i logged a support ticket for this problem recently and was provided with an updated js file

That is possible. I haven't had a chance to look into it yet so I don't know. Thanks for the suggestion though, I'll check early to see if that is the problem.

Make that 3 people that have had this problem.
I'm at a standstill on my development now.
Haven't called in. No ticket number.
Waiting to see what happens in this thread.

Try the solution listed at: showthread.php?t=145

I think it is most likely the cause.
